Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556872, here are decompositions:

5 + 556867 = 556872
11 + 556861 = 556872
13 + 556859 = 556872
23 + 556849 = 556872
31 + 556841 = 556872
53 + 556819 = 556872
61 + 556811 = 556872
73 + 556799 = 556872

Showing the first eight; more decompositions exist.
