Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604566, here are decompositions:

5 + 31604561 = 31604566
113 + 31604453 = 31604566
179 + 31604387 = 31604566
263 + 31604303 = 31604566
269 + 31604297 = 31604566
347 + 31604219 = 31604566
467 + 31604099 = 31604566
509 + 31604057 = 31604566

Showing the first eight; more decompositions exist.
