Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666986, here are decompositions:

47 + 8666939 = 8666986
59 + 8666927 = 8666986
137 + 8666849 = 8666986
179 + 8666807 = 8666986
239 + 8666747 = 8666986
359 + 8666627 = 8666986
389 + 8666597 = 8666986
443 + 8666543 = 8666986

Showing the first eight; more decompositions exist.
