Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604622, here are decompositions:

11 + 31604611 = 31604622
13 + 31604609 = 31604622
19 + 31604603 = 31604622
61 + 31604561 = 31604622
89 + 31604533 = 31604622
113 + 31604509 = 31604622
239 + 31604383 = 31604622
251 + 31604371 = 31604622

Showing the first eight; more decompositions exist.
