Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604424, here are decompositions:

37 + 31604387 = 31604424
41 + 31604383 = 31604424
53 + 31604371 = 31604424
67 + 31604357 = 31604424
83 + 31604341 = 31604424
113 + 31604311 = 31604424
127 + 31604297 = 31604424
197 + 31604227 = 31604424

Showing the first eight; more decompositions exist.
