Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460764, here are decompositions:

47 + 31460717 = 31460764
107 + 31460657 = 31460764
227 + 31460537 = 31460764
281 + 31460483 = 31460764
443 + 31460321 = 31460764
701 + 31460063 = 31460764
827 + 31459937 = 31460764
911 + 31459853 = 31460764

Showing the first eight; more decompositions exist.
