Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604120, here are decompositions:

241 + 31603879 = 31604120
277 + 31603843 = 31604120
409 + 31603711 = 31604120
439 + 31603681 = 31604120
463 + 31603657 = 31604120
601 + 31603519 = 31604120
631 + 31603489 = 31604120
727 + 31603393 = 31604120

Showing the first eight; more decompositions exist.
