Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556626, here are decompositions:

13 + 556613 = 556626
17 + 556609 = 556626
19 + 556607 = 556626
43 + 556583 = 556626
47 + 556579 = 556626
53 + 556573 = 556626
67 + 556559 = 556626
89 + 556537 = 556626

Showing the first eight; more decompositions exist.
