Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655982, here are decompositions:

29 + 8655953 = 8655982
59 + 8655923 = 8655982
113 + 8655869 = 8655982
173 + 8655809 = 8655982
233 + 8655749 = 8655982
263 + 8655719 = 8655982
281 + 8655701 = 8655982
311 + 8655671 = 8655982

Showing the first eight; more decompositions exist.
