Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666256, here are decompositions:

19 + 8666237 = 8666256
37 + 8666219 = 8666256
73 + 8666183 = 8666256
83 + 8666173 = 8666256
89 + 8666167 = 8666256
97 + 8666159 = 8666256
103 + 8666153 = 8666256
163 + 8666093 = 8666256

Showing the first eight; more decompositions exist.
