Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604512, here are decompositions:

3 + 31604509 = 31604512
11 + 31604501 = 31604512
59 + 31604453 = 31604512
293 + 31604219 = 31604512
383 + 31604129 = 31604512
461 + 31604051 = 31604512
479 + 31604033 = 31604512
521 + 31603991 = 31604512

Showing the first eight; more decompositions exist.
