P.S. I'm puzzled by this statement about these twin primes at that link: ----- They will enter Chris Caldwell's “The Largest Known Primes Database” (http://primes.utm.edu/primes) ranked 1st for twins, and each entered individually ranked 4180th overall. ----- Why do they have the same ranking overall? Does it not matter that one is bigger than the other? —Dan

Is anything known about the factorization of that coefficient
(other than its divisibility by 5 and 9)?
Was it chosen as part of some algorithm that singled out relatively likely candidates? Or was it just stumbled on at random from a massive search?
Or maybe one of our factoring experts can factor it? (You know who you are.)
