Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604356, here are decompositions:

53 + 31604303 = 31604356
59 + 31604297 = 31604356
137 + 31604219 = 31604356
167 + 31604189 = 31604356
227 + 31604129 = 31604356
257 + 31604099 = 31604356
467 + 31603889 = 31604356
479 + 31603877 = 31604356

Showing the first eight; more decompositions exist.
