Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556886, here are decompositions:

3 + 556883 = 556886
19 + 556867 = 556886
37 + 556849 = 556886
67 + 556819 = 556886
97 + 556789 = 556886
163 + 556723 = 556886
193 + 556693 = 556886
199 + 556687 = 556886

Showing the first eight; more decompositions exist.
