Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631008, here are decompositions:

7 + 8631001 = 8631008
37 + 8630971 = 8631008
79 + 8630929 = 8631008
109 + 8630899 = 8631008
151 + 8630857 = 8631008
157 + 8630851 = 8631008
229 + 8630779 = 8631008
271 + 8630737 = 8631008

Showing the first eight; more decompositions exist.
