Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604758, here are decompositions:

11 + 31604747 = 31604758
71 + 31604687 = 31604758
131 + 31604627 = 31604758
149 + 31604609 = 31604758
197 + 31604561 = 31604758
257 + 31604501 = 31604758
401 + 31604357 = 31604758
461 + 31604297 = 31604758

Showing the first eight; more decompositions exist.
