Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596338, here are decompositions:

31 + 31596307 = 31596338
211 + 31596127 = 31596338
271 + 31596067 = 31596338
331 + 31596007 = 31596338
349 + 31595989 = 31596338
409 + 31595929 = 31596338
457 + 31595881 = 31596338
607 + 31595731 = 31596338

Showing the first eight; more decompositions exist.
