Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631108, here are decompositions:

11 + 8631097 = 8631108
67 + 8631041 = 8631108
71 + 8631037 = 8631108
97 + 8631011 = 8631108
107 + 8631001 = 8631108
137 + 8630971 = 8631108
179 + 8630929 = 8631108
251 + 8630857 = 8631108

Showing the first eight; more decompositions exist.
