Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514290, here are decompositions:

23 + 31514267 = 31514290
29 + 31514261 = 31514290
131 + 31514159 = 31514290
347 + 31513943 = 31514290
503 + 31513787 = 31514290
569 + 31513721 = 31514290
593 + 31513697 = 31514290
677 + 31513613 = 31514290

Showing the first eight; more decompositions exist.
