Mathematically, this is a very remote possibility, as factoring primes
is probably an NP problem, and P is probably not NP. Neither of these
has been proven, however.
Even allowing for the miniscule possibility that there is a shortcut
to factoring primes, that doesn't necessarily mean that factoring huge
primes will be an easy task. Using larger keys will still provide a
measure of security.

Factoring primes is a solved problem. You probably mean "factoring the
product of two large primes".
