Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514032, here are decompositions:

89 + 31513943 = 31514032
239 + 31513793 = 31514032
293 + 31513739 = 31514032
311 + 31513721 = 31514032
419 + 31513613 = 31514032
659 + 31513373 = 31514032
701 + 31513331 = 31514032
773 + 31513259 = 31514032

Showing the first eight; more decompositions exist.
