Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666776, here are decompositions:

3 + 8666773 = 8666776
29 + 8666747 = 8666776
149 + 8666627 = 8666776
179 + 8666597 = 8666776
233 + 8666543 = 8666776
257 + 8666519 = 8666776
263 + 8666513 = 8666776
317 + 8666459 = 8666776

Showing the first eight; more decompositions exist.
