Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514074, here are decompositions:

107 + 31513967 = 31514074
131 + 31513943 = 31514074
197 + 31513877 = 31514074
257 + 31513817 = 31514074
281 + 31513793 = 31514074
353 + 31513721 = 31514074
461 + 31513613 = 31514074
467 + 31513607 = 31514074

Showing the first eight; more decompositions exist.
