Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631320, here are decompositions:

13 + 8631307 = 8631320
37 + 8631283 = 8631320
43 + 8631277 = 8631320
73 + 8631247 = 8631320
127 + 8631193 = 8631320
211 + 8631109 = 8631320
223 + 8631097 = 8631320
283 + 8631037 = 8631320

Showing the first eight; more decompositions exist.
