Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656266, here are decompositions:

13 + 8656253 = 8656266
89 + 8656177 = 8656266
97 + 8656169 = 8656266
103 + 8656163 = 8656266
107 + 8656159 = 8656266
137 + 8656129 = 8656266
149 + 8656117 = 8656266
173 + 8656093 = 8656266

Showing the first eight; more decompositions exist.
