Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012868, here are decompositions:

7 + 1012861 = 1012868
37 + 1012831 = 1012868
79 + 1012789 = 1012868
97 + 1012771 = 1012868
151 + 1012717 = 1012868
211 + 1012657 = 1012868
271 + 1012597 = 1012868
277 + 1012591 = 1012868

Showing the first eight; more decompositions exist.
