Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646170, here are decompositions:

7 + 8646163 = 8646170
67 + 8646103 = 8646170
109 + 8646061 = 8646170
199 + 8645971 = 8646170
229 + 8645941 = 8646170
271 + 8645899 = 8646170
283 + 8645887 = 8646170
307 + 8645863 = 8646170

Showing the first eight; more decompositions exist.
