Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718166, here are decompositions:

3 + 8718163 = 8718166
53 + 8718113 = 8718166
167 + 8717999 = 8718166
173 + 8717993 = 8718166
179 + 8717987 = 8718166
227 + 8717939 = 8718166
239 + 8717927 = 8718166
257 + 8717909 = 8718166

Showing the first eight; more decompositions exist.
