Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040868, here are decompositions:

7 + 1040861 = 1040868
11 + 1040857 = 1040868
41 + 1040827 = 1040868
47 + 1040821 = 1040868
61 + 1040807 = 1040868
71 + 1040797 = 1040868
89 + 1040779 = 1040868
97 + 1040771 = 1040868

Showing the first eight; more decompositions exist.
