Comment (by nickm):

 Looks correctly written.  I'm not clear what exactly the threat model is
 here, though.  "We replace the primes with something we think is prime,
 but we forget to check"?  "An attacker backdoors our software but doesn't
 figure out how to remove this check, or can't for some reason"?
