Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604672, here are decompositions:

31 + 31604641 = 31604672
61 + 31604611 = 31604672
139 + 31604533 = 31604672
163 + 31604509 = 31604672
313 + 31604359 = 31604672
331 + 31604341 = 31604672
373 + 31604299 = 31604672
409 + 31604263 = 31604672

Showing the first eight; more decompositions exist.
