Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012828, here are decompositions:

17 + 1012811 = 1012828
59 + 1012769 = 1012828
107 + 1012721 = 1012828
137 + 1012691 = 1012828
149 + 1012679 = 1012828
191 + 1012637 = 1012828
197 + 1012631 = 1012828
227 + 1012601 = 1012828

Showing the first eight; more decompositions exist.
