Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556566, here are decompositions:

7 + 556559 = 556566
29 + 556537 = 556566
47 + 556519 = 556566
53 + 556513 = 556566
79 + 556487 = 556566
83 + 556483 = 556566
89 + 556477 = 556566
107 + 556459 = 556566

Showing the first eight; more decompositions exist.
