Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556746, here are decompositions:

5 + 556741 = 556746
19 + 556727 = 556746
23 + 556723 = 556746
37 + 556709 = 556746
53 + 556693 = 556746
59 + 556687 = 556746
67 + 556679 = 556746
107 + 556639 = 556746

Showing the first eight; more decompositions exist.
