Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604914, here are decompositions:

167 + 31604747 = 31604914
191 + 31604723 = 31604914
227 + 31604687 = 31604914
233 + 31604681 = 31604914
311 + 31604603 = 31604914
353 + 31604561 = 31604914
461 + 31604453 = 31604914
557 + 31604357 = 31604914

Showing the first eight; more decompositions exist.
