Primes are very common. So as long as you have a few bits to fiddle with in your file, you can probably make it a prime very quickly.

Given an arbitrary stopping point x, you have approximately x / log x primes between 1 and x.

In other words, for a file of length n, you have to try about O(n) slight variations to find a prime number.

A nice example are the drawings using prime numbers. For example see
