Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631126, here are decompositions:

17 + 8631109 = 8631126
29 + 8631097 = 8631126
43 + 8631083 = 8631126
89 + 8631037 = 8631126
103 + 8631023 = 8631126
109 + 8631017 = 8631126
197 + 8630929 = 8631126
223 + 8630903 = 8631126

Showing the first eight; more decompositions exist.
