Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596436, here are decompositions:

17 + 31596419 = 31596436
23 + 31596413 = 31596436
227 + 31596209 = 31596436
293 + 31596143 = 31596436
317 + 31596119 = 31596436
467 + 31595969 = 31596436
563 + 31595873 = 31596436
569 + 31595867 = 31596436

Showing the first eight; more decompositions exist.
