Double evaluation in recursive function

Hi all !

Does somebody know how to use 2 calls at a time in a recursive function...?

for example I want to evaluate the following

myf[x_] : =  If[ x > 5, i = x ; j = x ; i--; j--; myf[i]; myf[j] ]

I get the answer from
myf[7]

i=6
i=5
j=5
j=5

apparently Mathematica doesn't like much the second term myf[j], because it
start from 5 to 5 ! and not from 6 to 5 like variable i............how can I
manage such a problem ?

Thanx for any suggestion or advice.

Benoit.
