Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596454, here are decompositions:

17 + 31596437 = 31596454
41 + 31596413 = 31596454
53 + 31596401 = 31596454
137 + 31596317 = 31596454
311 + 31596143 = 31596454
587 + 31595867 = 31596454
647 + 31595807 = 31596454
677 + 31595777 = 31596454

Showing the first eight; more decompositions exist.
