Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012812, here are decompositions:

23 + 1012789 = 1012812
41 + 1012771 = 1012812
43 + 1012769 = 1012812
61 + 1012751 = 1012812
79 + 1012733 = 1012812
109 + 1012703 = 1012812
113 + 1012699 = 1012812
149 + 1012663 = 1012812

Showing the first eight; more decompositions exist.
