Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517530, here are decompositions:

17 + 517513 = 517530
19 + 517511 = 517530
23 + 517507 = 517530
29 + 517501 = 517530
31 + 517499 = 517530
43 + 517487 = 517530
59 + 517471 = 517530
61 + 517469 = 517530

Showing the first eight; more decompositions exist.
