Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012870, here are decompositions:

41 + 1012829 = 1012870
59 + 1012811 = 1012870
101 + 1012769 = 1012870
107 + 1012763 = 1012870
137 + 1012733 = 1012870
149 + 1012721 = 1012870
167 + 1012703 = 1012870
179 + 1012691 = 1012870

Showing the first eight; more decompositions exist.
