Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604144, here are decompositions:

7 + 31604137 = 31604144
157 + 31603987 = 31604144
211 + 31603933 = 31604144
433 + 31603711 = 31604144
463 + 31603681 = 31604144
487 + 31603657 = 31604144
577 + 31603567 = 31604144
751 + 31603393 = 31604144

Showing the first eight; more decompositions exist.
