Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027806, here are decompositions:

7 + 1027799 = 1027806
19 + 1027787 = 1027806
23 + 1027783 = 1027806
29 + 1027777 = 1027806
47 + 1027759 = 1027806
53 + 1027753 = 1027806
67 + 1027739 = 1027806
79 + 1027727 = 1027806

Showing the first eight; more decompositions exist.
