Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556650, here are decompositions:

11 + 556639 = 556650
23 + 556627 = 556650
37 + 556613 = 556650
41 + 556609 = 556650
43 + 556607 = 556650
67 + 556583 = 556650
71 + 556579 = 556650
113 + 556537 = 556650

Showing the first eight; more decompositions exist.
