Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639266, here are decompositions:

3 + 8639263 = 8639266
5 + 8639261 = 8639266
17 + 8639249 = 8639266
47 + 8639219 = 8639266
59 + 8639207 = 8639266
89 + 8639177 = 8639266
113 + 8639153 = 8639266
239 + 8639027 = 8639266

Showing the first eight; more decompositions exist.
