Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460776, here are decompositions:

47 + 31460729 = 31460776
59 + 31460717 = 31460776
167 + 31460609 = 31460776
227 + 31460549 = 31460776
239 + 31460537 = 31460776
293 + 31460483 = 31460776
509 + 31460267 = 31460776
647 + 31460129 = 31460776

Showing the first eight; more decompositions exist.
