Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514422, here are decompositions:

3 + 31514419 = 31514422
113 + 31514309 = 31514422
131 + 31514291 = 31514422
263 + 31514159 = 31514422
479 + 31513943 = 31514422
683 + 31513739 = 31514422
701 + 31513721 = 31514422
761 + 31513661 = 31514422

Showing the first eight; more decompositions exist.
