Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666764, here are decompositions:

17 + 8666747 = 8666764
53 + 8666711 = 8666764
83 + 8666681 = 8666764
137 + 8666627 = 8666764
167 + 8666597 = 8666764
173 + 8666591 = 8666764
251 + 8666513 = 8666764
263 + 8666501 = 8666764

Showing the first eight; more decompositions exist.
