Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012866, here are decompositions:

5 + 1012861 = 1012866
37 + 1012829 = 1012866
97 + 1012769 = 1012866
103 + 1012763 = 1012866
149 + 1012717 = 1012866
163 + 1012703 = 1012866
167 + 1012699 = 1012866
229 + 1012637 = 1012866

Showing the first eight; more decompositions exist.
