Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514056, here are decompositions:

89 + 31513967 = 31514056
113 + 31513943 = 31514056
179 + 31513877 = 31514056
239 + 31513817 = 31514056
263 + 31513793 = 31514056
269 + 31513787 = 31514056
317 + 31513739 = 31514056
347 + 31513709 = 31514056

Showing the first eight; more decompositions exist.
