Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604396, here are decompositions:

13 + 31604383 = 31604396
37 + 31604359 = 31604396
97 + 31604299 = 31604396
409 + 31603987 = 31604396
463 + 31603933 = 31604396
739 + 31603657 = 31604396
787 + 31603609 = 31604396
829 + 31603567 = 31604396

Showing the first eight; more decompositions exist.
