Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1010866, here are decompositions:

5 + 1010861 = 1010866
23 + 1010843 = 1010866
83 + 1010783 = 1010866
107 + 1010759 = 1010866
113 + 1010753 = 1010866
149 + 1010717 = 1010866
179 + 1010687 = 1010866
239 + 1010627 = 1010866

Showing the first eight; more decompositions exist.
