Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596284, here are decompositions:

157 + 31596127 = 31596284
163 + 31596121 = 31596284
277 + 31596007 = 31596284
613 + 31595671 = 31596284
631 + 31595653 = 31596284
673 + 31595611 = 31596284
691 + 31595593 = 31596284
877 + 31595407 = 31596284

Showing the first eight; more decompositions exist.
