Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604312, here are decompositions:

13 + 31604299 = 31604312
31 + 31604281 = 31604312
379 + 31603933 = 31604312
433 + 31603879 = 31604312
601 + 31603711 = 31604312
631 + 31603681 = 31604312
823 + 31603489 = 31604312
919 + 31603393 = 31604312

Showing the first eight; more decompositions exist.
