Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651166, here are decompositions:

5 + 8651161 = 8651166
23 + 8651143 = 8651166
47 + 8651119 = 8651166
103 + 8651063 = 8651166
127 + 8651039 = 8651166
149 + 8651017 = 8651166
157 + 8651009 = 8651166
239 + 8650927 = 8651166

Showing the first eight; more decompositions exist.
