Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604634, here are decompositions:

7 + 31604627 = 31604634
23 + 31604611 = 31604634
31 + 31604603 = 31604634
73 + 31604561 = 31604634
101 + 31604533 = 31604634
137 + 31604497 = 31604634
181 + 31604453 = 31604634
251 + 31604383 = 31604634

Showing the first eight; more decompositions exist.
