Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012872, here are decompositions:

11 + 1012861 = 1012872
41 + 1012831 = 1012872
43 + 1012829 = 1012872
61 + 1012811 = 1012872
83 + 1012789 = 1012872
101 + 1012771 = 1012872
103 + 1012769 = 1012872
109 + 1012763 = 1012872

Showing the first eight; more decompositions exist.
