Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556878, here are decompositions:

11 + 556867 = 556878
17 + 556861 = 556878
19 + 556859 = 556878
29 + 556849 = 556878
37 + 556841 = 556878
59 + 556819 = 556878
61 + 556817 = 556878
67 + 556811 = 556878

Showing the first eight; more decompositions exist.
