The original Turing machine is equivalent to any PC, apart from the
finiteness of the latter's storage.
So you could be asking for a /program/ to generate the primes, in which case
one could point to enumeration of the successive integers plus trial
factorisation as a guaranteed method, with sieve of Eratosthenes technology as a
speed-up, and so on.
If you want a set of instructions for the original type of TM, viz. a
read/write/erase head moving left and right over an infinite tape, then you will need
a lot of patience! as the execution times of such a machine, even for much
simpler algorithmic tasks, are horrendous.
Why would you want that?
