One problem is that busy CPUs consume more power than ones, so the
unused cycles aren't free. Another problem is that most CPU chips have
multiple cores, so keeping only one of them busy won't tell whether
there's a virus running on another one. So you have to keep all of the
cores busy. Combine the first problem with the second problem and you
a third potential problem: overheating.

But your proposed practical application of large primes doesn't answer
the question about their mathematical importance.
