Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556806, here are decompositions:

7 + 556799 = 556806
13 + 556793 = 556806
17 + 556789 = 556806
37 + 556769 = 556806
43 + 556763 = 556806
53 + 556753 = 556806
79 + 556727 = 556806
83 + 556723 = 556806

Showing the first eight; more decompositions exist.
