Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631006, here are decompositions:

5 + 8631001 = 8631006
23 + 8630983 = 8631006
103 + 8630903 = 8631006
107 + 8630899 = 8631006
149 + 8630857 = 8631006
173 + 8630833 = 8631006
193 + 8630813 = 8631006
227 + 8630779 = 8631006

Showing the first eight; more decompositions exist.
