Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556826, here are decompositions:

3 + 556823 = 556826
7 + 556819 = 556826
37 + 556789 = 556826
73 + 556753 = 556826
103 + 556723 = 556826
139 + 556687 = 556826
199 + 556627 = 556826
307 + 556519 = 556826

Showing the first eight; more decompositions exist.
