Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604582, here are decompositions:

73 + 31604509 = 31604582
199 + 31604383 = 31604582
211 + 31604371 = 31604582
223 + 31604359 = 31604582
241 + 31604341 = 31604582
271 + 31604311 = 31604582
283 + 31604299 = 31604582
739 + 31603843 = 31604582

Showing the first eight; more decompositions exist.
