Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1010820, here are decompositions:

11 + 1010809 = 1010820
23 + 1010797 = 1010820
29 + 1010791 = 1010820
37 + 1010783 = 1010820
53 + 1010767 = 1010820
61 + 1010759 = 1010820
67 + 1010753 = 1010820
71 + 1010749 = 1010820

Showing the first eight; more decompositions exist.
