Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631266, here are decompositions:

19 + 8631247 = 8631266
37 + 8631229 = 8631266
67 + 8631199 = 8631266
73 + 8631193 = 8631266
157 + 8631109 = 8631266
229 + 8631037 = 8631266
283 + 8630983 = 8631266
337 + 8630929 = 8631266

Showing the first eight; more decompositions exist.
