Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665678, here are decompositions:

11 + 8665667 = 8665678
29 + 8665649 = 8665678
59 + 8665619 = 8665678
107 + 8665571 = 8665678
137 + 8665541 = 8665678
179 + 8665499 = 8665678
227 + 8665451 = 8665678
269 + 8665409 = 8665678

Showing the first eight; more decompositions exist.
