Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604216, here are decompositions:

79 + 31604137 = 31604216
229 + 31603987 = 31604216
283 + 31603933 = 31604216
337 + 31603879 = 31604216
373 + 31603843 = 31604216
499 + 31603717 = 31604216
607 + 31603609 = 31604216
727 + 31603489 = 31604216

Showing the first eight; more decompositions exist.
