Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029866, here are decompositions:

7 + 1029859 = 1029866
43 + 1029823 = 1029866
109 + 1029757 = 1029866
223 + 1029643 = 1029866
283 + 1029583 = 1029866
349 + 1029517 = 1029866
367 + 1029499 = 1029866
379 + 1029487 = 1029866

Showing the first eight; more decompositions exist.
