Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556756, here are decompositions:

3 + 556753 = 556756
29 + 556727 = 556756
47 + 556709 = 556756
59 + 556697 = 556756
149 + 556607 = 556756
173 + 556583 = 556756
197 + 556559 = 556756
269 + 556487 = 556756

Showing the first eight; more decompositions exist.
