primality test binary

I'm generating numbers using a Java program (BigIntegers) and I want to know if there's a binary readily available that I could use to run primality tests on the numbers generated.... suppose I feed them through a pipe from my java program into the binary. Is it out there? I'm trying to find packages for aks on apt but I see nothing "straightforward", only libs that I could use to program stuff (like, based on GMP).
