Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604648, here are decompositions:

7 + 31604641 = 31604648
37 + 31604611 = 31604648
139 + 31604509 = 31604648
151 + 31604497 = 31604648
277 + 31604371 = 31604648
307 + 31604341 = 31604648
337 + 31604311 = 31604648
349 + 31604299 = 31604648

Showing the first eight; more decompositions exist.
