Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604794, here are decompositions:

5 + 31604789 = 31604794
47 + 31604747 = 31604794
71 + 31604723 = 31604794
107 + 31604687 = 31604794
113 + 31604681 = 31604794
167 + 31604627 = 31604794
191 + 31604603 = 31604794
233 + 31604561 = 31604794

Showing the first eight; more decompositions exist.
