Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655678, here are decompositions:

7 + 8655671 = 8655678
29 + 8655649 = 8655678
37 + 8655641 = 8655678
41 + 8655637 = 8655678
47 + 8655631 = 8655678
67 + 8655611 = 8655678
151 + 8655527 = 8655678
181 + 8655497 = 8655678

Showing the first eight; more decompositions exist.
