Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510090, here are decompositions:

11 + 31510079 = 31510090
83 + 31510007 = 31510090
89 + 31510001 = 31510090
149 + 31509941 = 31510090
197 + 31509893 = 31510090
239 + 31509851 = 31510090
317 + 31509773 = 31510090
431 + 31509659 = 31510090

Showing the first eight; more decompositions exist.
