Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463746, here are decompositions:

3 + 31463743 = 31463746
29 + 31463717 = 31463746
227 + 31463519 = 31463746
239 + 31463507 = 31463746
257 + 31463489 = 31463746
263 + 31463483 = 31463746
269 + 31463477 = 31463746
317 + 31463429 = 31463746

Showing the first eight; more decompositions exist.
