Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666718, here are decompositions:

7 + 8666711 = 8666718
37 + 8666681 = 8666718
127 + 8666591 = 8666718
199 + 8666519 = 8666718
227 + 8666491 = 8666718
239 + 8666479 = 8666718
241 + 8666477 = 8666718
331 + 8666387 = 8666718

Showing the first eight; more decompositions exist.
