Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017810, here are decompositions:

11 + 1017799 = 1017810
23 + 1017787 = 1017810
29 + 1017781 = 1017810
61 + 1017749 = 1017810
89 + 1017721 = 1017810
97 + 1017713 = 1017810
107 + 1017703 = 1017810
127 + 1017683 = 1017810

Showing the first eight; more decompositions exist.
