Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666698, here are decompositions:

17 + 8666681 = 8666698
71 + 8666627 = 8666698
101 + 8666597 = 8666698
107 + 8666591 = 8666698
179 + 8666519 = 8666698
197 + 8666501 = 8666698
239 + 8666459 = 8666698
281 + 8666417 = 8666698

Showing the first eight; more decompositions exist.
