Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604646, here are decompositions:

5 + 31604641 = 31604646
19 + 31604627 = 31604646
37 + 31604609 = 31604646
43 + 31604603 = 31604646
89 + 31604557 = 31604646
113 + 31604533 = 31604646
137 + 31604509 = 31604646
149 + 31604497 = 31604646

Showing the first eight; more decompositions exist.
