Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631256, here are decompositions:

5 + 8631251 = 8631256
89 + 8631167 = 8631256
173 + 8631083 = 8631256
233 + 8631023 = 8631256
239 + 8631017 = 8631256
353 + 8630903 = 8631256
419 + 8630837 = 8631256
443 + 8630813 = 8631256

Showing the first eight; more decompositions exist.
