Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666748, here are decompositions:

37 + 8666711 = 8666748
67 + 8666681 = 8666748
151 + 8666597 = 8666748
157 + 8666591 = 8666748
229 + 8666519 = 8666748
257 + 8666491 = 8666748
269 + 8666479 = 8666748
271 + 8666477 = 8666748

Showing the first eight; more decompositions exist.
