Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666366, here are decompositions:

19 + 8666347 = 8666366
43 + 8666323 = 8666366
97 + 8666269 = 8666366
193 + 8666173 = 8666366
199 + 8666167 = 8666366
229 + 8666137 = 8666366
307 + 8666059 = 8666366
349 + 8666017 = 8666366

Showing the first eight; more decompositions exist.
