Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012986, here are decompositions:

5 + 1012981 = 1012986
19 + 1012967 = 1012986
67 + 1012919 = 1012986
83 + 1012903 = 1012986
157 + 1012829 = 1012986
197 + 1012789 = 1012986
223 + 1012763 = 1012986
269 + 1012717 = 1012986

Showing the first eight; more decompositions exist.
