Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514254, here are decompositions:

173 + 31514081 = 31514254
311 + 31513943 = 31514254
461 + 31513793 = 31514254
467 + 31513787 = 31514254
557 + 31513697 = 31514254
587 + 31513667 = 31514254
593 + 31513661 = 31514254
641 + 31513613 = 31514254

Showing the first eight; more decompositions exist.
