Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464124, here are decompositions:

227 + 31463897 = 31464124
233 + 31463891 = 31464124
281 + 31463843 = 31464124
317 + 31463807 = 31464124
443 + 31463681 = 31464124
617 + 31463507 = 31464124
641 + 31463483 = 31464124
647 + 31463477 = 31464124

Showing the first eight; more decompositions exist.
