Yes, I seem to have come up with a way to factor the Zeta function into 
five parts. It also seem to work on other functions.

Using: "n_Integer?Positive" gets rid of the error signal too.
Here are harmonic functions "deconstructed" into nearly orthogonal
sines and cosines.

f[n_Integer?Positive, 1] := If[Mod[Prime[n], 12] - 1 == 0, n!, 0]
f[n_Integer?Positive, 2] := If[Mod[Prime[n], 12] - 5 == 0, n!, 0]
f[n_Integer?Positive, 3] := If[Mod[Prime[n], 12] - 7 == 0, n!, 0]
f[n_Integer?Positive, 4] := If[Mod[Prime[n], 12] - 11 == 0, n!, 0]
CosM[x_, m_Integer?Positive] := Sum[If[f[2*n, m] == 0,
   0, (-1)^n*x^(2*n)/f[2*n, m]], {n, 1, 200}]
SinM[x_, m_Integer?Positive] := Sum[If[f[2*n + 1, m] == 0, 0, (-1)^n*x^(2*
     n + 1)/f[2*n + 1, m]], {n, 1, 200}]
ac = Table[Plot[CosM[x, m], {x, -Pi, Pi}, PlotRange -> All], {m, 1, 4}]
as = Table[Plot[SinM[x, m], {x, -Pi, Pi}, PlotRange -> All], {m, 1, 4}]


This result gave me the idea that maybe the the primes were behaving 
like polarized light. Here is my experiment of this morning in that 
"light": ( you will note the orthogonality condition holds:
ai[n]*aj[n]=0 i,j={1,5,7,11}  )

(* appearance functional vectors for Primes Mudulo 12*)
a1[n_Integer?Positive] := If[Mod[Prime[n], 12] - 1 == 0, 1, 0]
a5[n_Integer?Positive] := If[Mod[Prime[n], 12] - 5 == 0, 1, 0]
a7[n_Integer?Positive] := If[Mod[Prime[n], 12] - 7 == 0, 1, 0]
a11[n_Integer?Positive] := If[Mod[Prime[n], 12] - 11 == 0, 1, 0]
(*Phase vectors relative to primes modulo 12 ending in one*)
p5[n_Integer?Positive] := If[a1[n] - 1 == 0,
   a1[n]*a5[n + 1] + a1[n]*a5[n + 2] + a1[n]*a5[n + 3], 0]
p7[n_Integer?Positive] := If[a1[n] - 1 == 0, a1[n]*a7[n + 1] + a1[n]*a7[
   n + 2] + a1[n]*a7[n + 3], 0]
p11[n_Integer?Positive] := If[a1[n] -
     1 == 0, a1[n]*a11[n + 1] + a1[n]*a11[n + 2] + a1[n]*a11[n + 3], 0]
(* Average phase functions *)
PA5[m_Integer?Positive] := (4/m)*Sum[a1[n]*p5[n], {n, 1.m}]
PA7[m_Integer?Positive] := (4/m)*Sum[a1[n]*p7[n], {n, 1.m}]
PA11[m_Integer?Positive] := (4/m)*Sum[a1[n]*p11[n], {n, 1.m}]
Digits = 1000
a = Table[PA5[n], {n, 1, Digits}];
ListPlot[a]
b = Table[PA7[n], {n, 1, Digits}];
ListPlot[b]
c = Table[PA11[n], {n, 1, Digits}];
ListPlot[c]
w = Table[Point[{a[[n]], b[[n]], c[[n]]}], {n, 1, Digits}];
Show[Graphics3D[{PointSize[0.005], w}]]

In this experiment after a large number it becomes apparent that 5 and 
11 ending modulo 12 primes behave at very close to the same phase angle.
I had done other experiments after finding that even and odd primes 
behaved differently in modulo 12 that showed a pairing effect of types 
{1,7},{5,11}
So that you get complex pairs of Sines and Cosines like :
C1+I*S5
C7+I*S11
Using the above functions:
x0 := 10*CosM[t, 1]*CosM[p, 3];
y0 := SinM[t, 2]*CosM[p, 3]
z0 := SinM[p, 4]
ParametricPlot3D[{z0, y0, x0}, {t, -Pi, Pi}, {p, -Pi,
    Pi}, PlotPoints -> {40, 40}, Boxed -> False, Axes -> False]

Which appears to be an interesting new surface.

It is interesting that such n! factorial based function are most 
dependent on the initial area where these  phases are most chaotic.
