Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654986, here are decompositions:

5 + 8654981 = 8654986
89 + 8654897 = 8654986
113 + 8654873 = 8654986
149 + 8654837 = 8654986
227 + 8654759 = 8654986
233 + 8654753 = 8654986
257 + 8654729 = 8654986
443 + 8654543 = 8654986

Showing the first eight; more decompositions exist.
