Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049866, here are decompositions:

3 + 1049863 = 1049866
5 + 1049861 = 1049866
17 + 1049849 = 1049866
23 + 1049843 = 1049866
29 + 1049837 = 1049866
149 + 1049717 = 1049866
179 + 1049687 = 1049866
227 + 1049639 = 1049866

Showing the first eight; more decompositions exist.
