Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604466, here are decompositions:

13 + 31604453 = 31604466
79 + 31604387 = 31604466
83 + 31604383 = 31604466
107 + 31604359 = 31604466
109 + 31604357 = 31604466
163 + 31604303 = 31604466
167 + 31604299 = 31604466
239 + 31604227 = 31604466

Showing the first eight; more decompositions exist.
