Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556822, here are decompositions:

3 + 556819 = 556822
5 + 556817 = 556822
11 + 556811 = 556822
23 + 556799 = 556822
29 + 556793 = 556822
41 + 556781 = 556822
53 + 556769 = 556822
59 + 556763 = 556822

Showing the first eight; more decompositions exist.
