Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666226, here are decompositions:

7 + 8666219 = 8666226
43 + 8666183 = 8666226
53 + 8666173 = 8666226
59 + 8666167 = 8666226
67 + 8666159 = 8666226
73 + 8666153 = 8666226
89 + 8666137 = 8666226
157 + 8666069 = 8666226

Showing the first eight; more decompositions exist.
