Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678966, here are decompositions:

3 + 8678963 = 8678966
19 + 8678947 = 8678966
67 + 8678899 = 8678966
73 + 8678893 = 8678966
103 + 8678863 = 8678966
193 + 8678773 = 8678966
367 + 8678599 = 8678966
379 + 8678587 = 8678966

Showing the first eight; more decompositions exist.
