Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604470, here are decompositions:

17 + 31604453 = 31604470
83 + 31604387 = 31604470
113 + 31604357 = 31604470
167 + 31604303 = 31604470
173 + 31604297 = 31604470
251 + 31604219 = 31604470
281 + 31604189 = 31604470
419 + 31604051 = 31604470

Showing the first eight; more decompositions exist.
