Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556908, here are decompositions:

17 + 556891 = 556908
41 + 556867 = 556908
47 + 556861 = 556908
59 + 556849 = 556908
67 + 556841 = 556908
89 + 556819 = 556908
97 + 556811 = 556908
109 + 556799 = 556908

Showing the first eight; more decompositions exist.
