Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604228, here are decompositions:

37 + 31604191 = 31604228
241 + 31603987 = 31604228
349 + 31603879 = 31604228
547 + 31603681 = 31604228
571 + 31603657 = 31604228
619 + 31603609 = 31604228
661 + 31603567 = 31604228
709 + 31603519 = 31604228

Showing the first eight; more decompositions exist.
