Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631156, here are decompositions:

5 + 8631151 = 8631156
47 + 8631109 = 8631156
59 + 8631097 = 8631156
73 + 8631083 = 8631156
139 + 8631017 = 8631156
173 + 8630983 = 8631156
227 + 8630929 = 8631156
257 + 8630899 = 8631156

Showing the first eight; more decompositions exist.
