Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609986, here are decompositions:

23 + 8609963 = 8609986
59 + 8609927 = 8609986
107 + 8609879 = 8609986
137 + 8609849 = 8609986
167 + 8609819 = 8609986
173 + 8609813 = 8609986
233 + 8609753 = 8609986
257 + 8609729 = 8609986

Showing the first eight; more decompositions exist.
