Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514050, here are decompositions:

83 + 31513967 = 31514050
107 + 31513943 = 31514050
173 + 31513877 = 31514050
233 + 31513817 = 31514050
257 + 31513793 = 31514050
263 + 31513787 = 31514050
311 + 31513739 = 31514050
353 + 31513697 = 31514050

Showing the first eight; more decompositions exist.
