Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604264, here are decompositions:

37 + 31604227 = 31604264
73 + 31604191 = 31604264
127 + 31604137 = 31604264
277 + 31603987 = 31604264
331 + 31603933 = 31604264
421 + 31603843 = 31604264
463 + 31603801 = 31604264
547 + 31603717 = 31604264

Showing the first eight; more decompositions exist.
