Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604810, here are decompositions:

7 + 31604803 = 31604810
43 + 31604767 = 31604810
67 + 31604743 = 31604810
79 + 31604731 = 31604810
163 + 31604647 = 31604810
199 + 31604611 = 31604810
277 + 31604533 = 31604810
313 + 31604497 = 31604810

Showing the first eight; more decompositions exist.
