Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513540, here are decompositions:

7 + 513533 = 513540
11 + 513529 = 513540
29 + 513511 = 513540
31 + 513509 = 513540
59 + 513481 = 513540
61 + 513479 = 513540
67 + 513473 = 513540
101 + 513439 = 513540

Showing the first eight; more decompositions exist.
