Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645986, here are decompositions:

5 + 8645981 = 8645986
59 + 8645927 = 8645986
137 + 8645849 = 8645986
197 + 8645789 = 8645986
227 + 8645759 = 8645986
257 + 8645729 = 8645986
317 + 8645669 = 8645986
353 + 8645633 = 8645986

Showing the first eight; more decompositions exist.
