Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018680, here are decompositions:

7 + 1018673 = 1018680
11 + 1018669 = 1018680
29 + 1018651 = 1018680
31 + 1018649 = 1018680
37 + 1018643 = 1018680
59 + 1018621 = 1018680
67 + 1018613 = 1018680
97 + 1018583 = 1018680

Showing the first eight; more decompositions exist.
