Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604306, here are decompositions:

3 + 31604303 = 31604306
7 + 31604299 = 31604306
43 + 31604263 = 31604306
79 + 31604227 = 31604306
373 + 31603933 = 31604306
463 + 31603843 = 31604306
739 + 31603567 = 31604306
787 + 31603519 = 31604306

Showing the first eight; more decompositions exist.
