Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637678, here are decompositions:

11 + 8637667 = 8637678
37 + 8637641 = 8637678
41 + 8637637 = 8637678
59 + 8637619 = 8637678
61 + 8637617 = 8637678
67 + 8637611 = 8637678
151 + 8637527 = 8637678
157 + 8637521 = 8637678

Showing the first eight; more decompositions exist.
