Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556620, here are decompositions:

7 + 556613 = 556620
11 + 556609 = 556620
13 + 556607 = 556620
19 + 556601 = 556620
37 + 556583 = 556620
41 + 556579 = 556620
47 + 556573 = 556620
61 + 556559 = 556620

Showing the first eight; more decompositions exist.
