Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514494, here are decompositions:

17 + 31514477 = 31514494
71 + 31514423 = 31514494
197 + 31514297 = 31514494
227 + 31514267 = 31514494
233 + 31514261 = 31514494
617 + 31513877 = 31514494
677 + 31513817 = 31514494
701 + 31513793 = 31514494

Showing the first eight; more decompositions exist.
