Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656166, here are decompositions:

3 + 8656163 = 8656166
7 + 8656159 = 8656166
19 + 8656147 = 8656166
37 + 8656129 = 8656166
73 + 8656093 = 8656166
97 + 8656069 = 8656166
109 + 8656057 = 8656166
199 + 8655967 = 8656166

Showing the first eight; more decompositions exist.
