Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739678, here are decompositions:

5 + 8739673 = 8739678
7 + 8739671 = 8739678
11 + 8739667 = 8739678
41 + 8739637 = 8739678
61 + 8739617 = 8739678
71 + 8739607 = 8739678
149 + 8739529 = 8739678
179 + 8739499 = 8739678

Showing the first eight; more decompositions exist.
