Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604258, here are decompositions:

31 + 31604227 = 31604258
67 + 31604191 = 31604258
271 + 31603987 = 31604258
379 + 31603879 = 31604258
457 + 31603801 = 31604258
541 + 31603717 = 31604258
547 + 31603711 = 31604258
577 + 31603681 = 31604258

Showing the first eight; more decompositions exist.
