Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027986, here are decompositions:

17 + 1027969 = 1027986
103 + 1027883 = 1027986
199 + 1027787 = 1027986
227 + 1027759 = 1027986
229 + 1027757 = 1027986
233 + 1027753 = 1027986
269 + 1027717 = 1027986
283 + 1027703 = 1027986

Showing the first eight; more decompositions exist.
