Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556724, here are decompositions:

31 + 556693 = 556724
37 + 556687 = 556724
73 + 556651 = 556724
97 + 556627 = 556724
151 + 556573 = 556724
211 + 556513 = 556724
241 + 556483 = 556724
283 + 556441 = 556724

Showing the first eight; more decompositions exist.
