Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659678, here are decompositions:

11 + 8659667 = 8659678
47 + 8659631 = 8659678
89 + 8659589 = 8659678
389 + 8659289 = 8659678
557 + 8659121 = 8659678
617 + 8659061 = 8659678
641 + 8659037 = 8659678
659 + 8659019 = 8659678

Showing the first eight; more decompositions exist.
