Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027818, here are decompositions:

19 + 1027799 = 1027818
31 + 1027787 = 1027818
41 + 1027777 = 1027818
59 + 1027759 = 1027818
61 + 1027757 = 1027818
67 + 1027751 = 1027818
79 + 1027739 = 1027818
101 + 1027717 = 1027818

Showing the first eight; more decompositions exist.
