Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626588, here are decompositions:

17 + 31626571 = 31626588
31 + 31626557 = 31626588
41 + 31626547 = 31626588
89 + 31626499 = 31626588
107 + 31626481 = 31626588
127 + 31626461 = 31626588
151 + 31626437 = 31626588
167 + 31626421 = 31626588

Showing the first eight; more decompositions exist.
