Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604084, here are decompositions:

97 + 31603987 = 31604084
151 + 31603933 = 31604084
241 + 31603843 = 31604084
283 + 31603801 = 31604084
367 + 31603717 = 31604084
373 + 31603711 = 31604084
691 + 31603393 = 31604084
823 + 31603261 = 31604084

Showing the first eight; more decompositions exist.
