since this does not relate to tetration , ill post it here.

it is easy to construct functions f(x) such that f(x) is analytic for REAL x > 1 and f(p) = 0 IFF p is a prime.

something looking similar to sin(pi x)^2 + sin( gamma(x)/x pi )^2 for instance.

however , it seems harder to find an entire function f(z) that satisfies f(z) = 0 IFF COMPLEX z = prime.

i heard about zeta functions and L-series , but i was thinking about simpler solutions.
