Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671218, here are decompositions:

41 + 8671177 = 8671218
67 + 8671151 = 8671218
71 + 8671147 = 8671218
151 + 8671067 = 8671218
167 + 8671051 = 8671218
211 + 8671007 = 8671218
229 + 8670989 = 8671218
271 + 8670947 = 8671218

Showing the first eight; more decompositions exist.
