Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681266, here are decompositions:

3 + 8681263 = 8681266
23 + 8681243 = 8681266
53 + 8681213 = 8681266
59 + 8681207 = 8681266
89 + 8681177 = 8681266
107 + 8681159 = 8681266
137 + 8681129 = 8681266
149 + 8681117 = 8681266

Showing the first eight; more decompositions exist.
