Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604108, here are decompositions:

229 + 31603879 = 31604108
307 + 31603801 = 31604108
397 + 31603711 = 31604108
499 + 31603609 = 31604108
541 + 31603567 = 31604108
619 + 31603489 = 31604108
727 + 31603381 = 31604108
859 + 31603249 = 31604108

Showing the first eight; more decompositions exist.
