Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631170, here are decompositions:

3 + 8631167 = 8631170
19 + 8631151 = 8631170
61 + 8631109 = 8631170
73 + 8631097 = 8631170
199 + 8630971 = 8631170
241 + 8630929 = 8631170
271 + 8630899 = 8631170
313 + 8630857 = 8631170

Showing the first eight; more decompositions exist.
