Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604812, here are decompositions:

23 + 31604789 = 31604812
53 + 31604759 = 31604812
89 + 31604723 = 31604812
131 + 31604681 = 31604812
251 + 31604561 = 31604812
311 + 31604501 = 31604812
359 + 31604453 = 31604812
509 + 31604303 = 31604812

Showing the first eight; more decompositions exist.
