Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8599666, here are decompositions:

17 + 8599649 = 8599666
59 + 8599607 = 8599666
83 + 8599583 = 8599666
107 + 8599559 = 8599666
113 + 8599553 = 8599666
197 + 8599469 = 8599666
227 + 8599439 = 8599666
263 + 8599403 = 8599666

Showing the first eight; more decompositions exist.
