Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659930, here are decompositions:

3 + 8659927 = 8659930
17 + 8659913 = 8659930
137 + 8659793 = 8659930
239 + 8659691 = 8659930
263 + 8659667 = 8659930
467 + 8659463 = 8659930
641 + 8659289 = 8659930
809 + 8659121 = 8659930

Showing the first eight; more decompositions exist.
