Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718666, here are decompositions:

17 + 8718649 = 8718666
127 + 8718539 = 8718666
163 + 8718503 = 8718666
179 + 8718487 = 8718666
197 + 8718469 = 8718666
227 + 8718439 = 8718666
239 + 8718427 = 8718666
317 + 8718349 = 8718666

Showing the first eight; more decompositions exist.
