Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666326, here are decompositions:

3 + 8666323 = 8666326
89 + 8666237 = 8666326
107 + 8666219 = 8666326
167 + 8666159 = 8666326
173 + 8666153 = 8666326
233 + 8666093 = 8666326
257 + 8666069 = 8666326
269 + 8666057 = 8666326

Showing the first eight; more decompositions exist.
