Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672218, here are decompositions:

11 + 8672207 = 8672218
17 + 8672201 = 8672218
41 + 8672177 = 8672218
101 + 8672117 = 8672218
131 + 8672087 = 8672218
227 + 8671991 = 8672218
239 + 8671979 = 8672218
251 + 8671967 = 8672218

Showing the first eight; more decompositions exist.
