Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604650, here are decompositions:

3 + 31604647 = 31604650
23 + 31604627 = 31604650
41 + 31604609 = 31604650
47 + 31604603 = 31604650
89 + 31604561 = 31604650
149 + 31604501 = 31604650
197 + 31604453 = 31604650
263 + 31604387 = 31604650

Showing the first eight; more decompositions exist.
