Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604078, here are decompositions:

199 + 31603879 = 31604078
277 + 31603801 = 31604078
367 + 31603711 = 31604078
397 + 31603681 = 31604078
421 + 31603657 = 31604078
769 + 31603309 = 31604078
829 + 31603249 = 31604078
937 + 31603141 = 31604078

Showing the first eight; more decompositions exist.
