Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604018, here are decompositions:

31 + 31603987 = 31604018
139 + 31603879 = 31604018
307 + 31603711 = 31604018
337 + 31603681 = 31604018
409 + 31603609 = 31604018
499 + 31603519 = 31604018
709 + 31603309 = 31604018
757 + 31603261 = 31604018

Showing the first eight; more decompositions exist.
