Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517620, here are decompositions:

7 + 517613 = 517620
11 + 517609 = 517620
17 + 517603 = 517620
23 + 517597 = 517620
31 + 517589 = 517620
43 + 517577 = 517620
67 + 517553 = 517620
71 + 517549 = 517620

Showing the first eight; more decompositions exist.
