Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556656, here are decompositions:

5 + 556651 = 556656
17 + 556639 = 556656
29 + 556627 = 556656
43 + 556613 = 556656
47 + 556609 = 556656
73 + 556583 = 556656
83 + 556573 = 556656
97 + 556559 = 556656

Showing the first eight; more decompositions exist.
