Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681166, here are decompositions:

7 + 8681159 = 8681166
37 + 8681129 = 8681166
89 + 8681077 = 8681166
107 + 8681059 = 8681166
157 + 8681009 = 8681166
163 + 8681003 = 8681166
173 + 8680993 = 8681166
227 + 8680939 = 8681166

Showing the first eight; more decompositions exist.
