I do not see an explanation of the method that allows for an analysis. As far as I know there is no known method for integer factorization that runs in polynomial time on classical* computers. "Large" is also rather vague.  

For quantum computers refer to Shor's algorithm: https://en.wikipedia.org/wiki/Shor's_algorithm

It is possible, if we restrict ourselves to prime factorization we know that the distribution of primes is strictly increasing (if looking at the largest and second largest primes we know of the gap is fairly large). We can assume that after some point x the number of primes to test should be small enough to run in polynomial time using known algorithms. We just use a hashmap for the ones before that and we have an algorithm that has a polynomial runtime.

The largest known primes are Mersenne primes. You have no idea where are non-Mersenne primes prior it..

Unless rafael returns and explains his wallpaper designs, the answer is no.

Can you provide a reference? As far as I know the best algorithm at this time is general number field sieve and it does not run in polynomial time.
