Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604564, here are decompositions:

3 + 31604561 = 31604564
7 + 31604557 = 31604564
31 + 31604533 = 31604564
67 + 31604497 = 31604564
181 + 31604383 = 31604564
193 + 31604371 = 31604564
223 + 31604341 = 31604564
283 + 31604281 = 31604564

Showing the first eight; more decompositions exist.
