Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666778, here are decompositions:

5 + 8666773 = 8666778
11 + 8666767 = 8666778
31 + 8666747 = 8666778
67 + 8666711 = 8666778
97 + 8666681 = 8666778
151 + 8666627 = 8666778
181 + 8666597 = 8666778
277 + 8666501 = 8666778

Showing the first eight; more decompositions exist.
