Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604368, here are decompositions:

11 + 31604357 = 31604368
71 + 31604297 = 31604368
149 + 31604219 = 31604368
179 + 31604189 = 31604368
239 + 31604129 = 31604368
269 + 31604099 = 31604368
311 + 31604057 = 31604368
317 + 31604051 = 31604368

Showing the first eight; more decompositions exist.
