Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604024, here are decompositions:

37 + 31603987 = 31604024
181 + 31603843 = 31604024
223 + 31603801 = 31604024
307 + 31603717 = 31604024
313 + 31603711 = 31604024
367 + 31603657 = 31604024
457 + 31603567 = 31604024
631 + 31603393 = 31604024

Showing the first eight; more decompositions exist.
