Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666266, here are decompositions:

29 + 8666237 = 8666266
47 + 8666219 = 8666266
83 + 8666183 = 8666266
107 + 8666159 = 8666266
113 + 8666153 = 8666266
173 + 8666093 = 8666266
197 + 8666069 = 8666266
239 + 8666027 = 8666266

Showing the first eight; more decompositions exist.
