Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514356, here are decompositions:

47 + 31514309 = 31514356
59 + 31514297 = 31514356
89 + 31514267 = 31514356
197 + 31514159 = 31514356
389 + 31513967 = 31514356
479 + 31513877 = 31514356
563 + 31513793 = 31514356
569 + 31513787 = 31514356

Showing the first eight; more decompositions exist.
