Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604448, here are decompositions:

61 + 31604387 = 31604448
89 + 31604359 = 31604448
101 + 31604347 = 31604448
107 + 31604341 = 31604448
137 + 31604311 = 31604448
149 + 31604299 = 31604448
151 + 31604297 = 31604448
167 + 31604281 = 31604448

Showing the first eight; more decompositions exist.
