Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517558, here are decompositions:

5 + 517553 = 517558
11 + 517547 = 517558
47 + 517511 = 517558
59 + 517499 = 517558
71 + 517487 = 517558
89 + 517469 = 517558
101 + 517457 = 517558
191 + 517367 = 517558

Showing the first eight; more decompositions exist.
