Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012878, here are decompositions:

17 + 1012861 = 1012878
47 + 1012831 = 1012878
67 + 1012811 = 1012878
89 + 1012789 = 1012878
107 + 1012771 = 1012878
109 + 1012769 = 1012878
127 + 1012751 = 1012878
157 + 1012721 = 1012878

Showing the first eight; more decompositions exist.
