Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604708, here are decompositions:

19 + 31604689 = 31604708
61 + 31604647 = 31604708
67 + 31604641 = 31604708
97 + 31604611 = 31604708
151 + 31604557 = 31604708
199 + 31604509 = 31604708
211 + 31604497 = 31604708
337 + 31604371 = 31604708

Showing the first eight; more decompositions exist.
