Default Repurposing 2 x 32Gh/s Bitcoin miners

Hi all, this is my first post here.

I own a pair of 32GH/s Bitcoin miners. They're specifically built and coded to mine Bitcoins and nothing else.

I remember reading previously that some had been repurposed as password crackers. This is of no interest to me, however if they can be repurposed as radically as that, can they be used in the search for large primes?

Incidentally, for those not familiar with Bitcoins and altcoins, there is a "Primecoin" that helps search for new primes. However to mine Primecoin you need GPU processing rather than CPU as with Bitcoin.

Has anyone repurposed a miner before and have instructions on how to begin? Would a budding coder like access to my miners to give it a trial? I'm not a coder and so very amateur in this field.

Thanks,

Sam.

Those are machines which use an ASIC; I can just about see that someone could have adapted them to do lots of SHA256 hashes quickly for password-cracking applications, though I suspect that would run more slowly than the mining, but they are useless for finding prime numbers.

Sorry.

There is also gapcoin that looks for first known occurrence large prime gaps. It is CPU (I think there is a GPU miner also, but it isn't massively faster), and would not benefit from fast hashing. The work is basically sieving and Fermat tests on 80-400 digit numbers.
