Hi

Your expression is stored as a multi-dimensional list.
Why dont you just assess the corresponding parts in it?

In[275]:=
exp=C[1]\[Epsilon] Integers&&x\[Equal]358537039003+2964364736430689
C[1]&&
    y\[Equal]28744265823+237656026328741 C[1]&&p\
[Equal]205319+1697566324 C[1]

Out[275]=
Integers \[Epsilon] C[1]&&x\[Equal]358537039003+2964364736430689
C[1]&&
  y\[Equal]28744265823+237656026328741 C[1]&&p\
[Equal]205319+1697566324 C[1]

In[283]:=
exp[[4,2,1]]

Out[283]=
205319

In[285]:=
exp[[4,2,2,1]]

Out[285]=
1697566324

Bye
