Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684986, here are decompositions:

3 + 8684983 = 8684986
5 + 8684981 = 8684986
47 + 8684939 = 8684986
83 + 8684903 = 8684986
113 + 8684873 = 8684986
197 + 8684789 = 8684986
227 + 8684759 = 8684986
239 + 8684747 = 8684986

Showing the first eight; more decompositions exist.
