Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631260, here are decompositions:

13 + 8631247 = 8631260
31 + 8631229 = 8631260
61 + 8631199 = 8631260
67 + 8631193 = 8631260
109 + 8631151 = 8631260
151 + 8631109 = 8631260
163 + 8631097 = 8631260
223 + 8631037 = 8631260

Showing the first eight; more decompositions exist.
