Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604256, here are decompositions:

29 + 31604227 = 31604256
37 + 31604219 = 31604256
67 + 31604189 = 31604256
127 + 31604129 = 31604256
157 + 31604099 = 31604256
199 + 31604057 = 31604256
223 + 31604033 = 31604256
269 + 31603987 = 31604256

Showing the first eight; more decompositions exist.
