Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631066, here are decompositions:

29 + 8631037 = 8631066
43 + 8631023 = 8631066
83 + 8630983 = 8631066
137 + 8630929 = 8631066
163 + 8630903 = 8631066
167 + 8630899 = 8631066
229 + 8630837 = 8631066
233 + 8630833 = 8631066

Showing the first eight; more decompositions exist.
