Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604836, here are decompositions:

47 + 31604789 = 31604836
89 + 31604747 = 31604836
113 + 31604723 = 31604836
149 + 31604687 = 31604836
227 + 31604609 = 31604836
233 + 31604603 = 31604836
383 + 31604453 = 31604836
449 + 31604387 = 31604836

Showing the first eight; more decompositions exist.
