Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672166, here are decompositions:

5 + 8672161 = 8672166
67 + 8672099 = 8672166
79 + 8672087 = 8672166
103 + 8672063 = 8672166
163 + 8672003 = 8672166
179 + 8671987 = 8672166
199 + 8671967 = 8672166
229 + 8671937 = 8672166

Showing the first eight; more decompositions exist.
