Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679644, here are decompositions:

3 + 8679641 = 8679644
37 + 8679607 = 8679644
271 + 8679373 = 8679644
367 + 8679277 = 8679644
373 + 8679271 = 8679644
607 + 8679037 = 8679644
751 + 8678893 = 8679644
811 + 8678833 = 8679644

Showing the first eight; more decompositions exist.
