Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006806, here are decompositions:

7 + 1006799 = 1006806
23 + 1006783 = 1006806
37 + 1006769 = 1006806
67 + 1006739 = 1006806
173 + 1006633 = 1006806
193 + 1006613 = 1006806
197 + 1006609 = 1006806
223 + 1006583 = 1006806

Showing the first eight; more decompositions exist.
