Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660678, here are decompositions:

7 + 8660671 = 8660678
67 + 8660611 = 8660678
109 + 8660569 = 8660678
139 + 8660539 = 8660678
151 + 8660527 = 8660678
211 + 8660467 = 8660678
241 + 8660437 = 8660678
277 + 8660401 = 8660678

Showing the first eight; more decompositions exist.
