Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042866, here are decompositions:

5 + 1042861 = 1042866
17 + 1042849 = 1042866
29 + 1042837 = 1042866
37 + 1042829 = 1042866
47 + 1042819 = 1042866
67 + 1042799 = 1042866
107 + 1042759 = 1042866
157 + 1042709 = 1042866

Showing the first eight; more decompositions exist.
