Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706678, here are decompositions:

7 + 8706671 = 8706678
11 + 8706667 = 8706678
31 + 8706647 = 8706678
67 + 8706611 = 8706678
109 + 8706569 = 8706678
131 + 8706547 = 8706678
151 + 8706527 = 8706678
181 + 8706497 = 8706678

Showing the first eight; more decompositions exist.
