Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026870, here are decompositions:

11 + 1026859 = 1026870
17 + 1026853 = 1026870
23 + 1026847 = 1026870
37 + 1026833 = 1026870
41 + 1026829 = 1026870
59 + 1026811 = 1026870
71 + 1026799 = 1026870
79 + 1026791 = 1026870

Showing the first eight; more decompositions exist.
