Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556644, here are decompositions:

5 + 556639 = 556644
17 + 556627 = 556644
31 + 556613 = 556644
37 + 556607 = 556644
43 + 556601 = 556644
61 + 556583 = 556644
71 + 556573 = 556644
107 + 556537 = 556644

Showing the first eight; more decompositions exist.
