Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512622, here are decompositions:

13 + 512609 = 512622
29 + 512593 = 512622
31 + 512591 = 512622
41 + 512581 = 512622
43 + 512579 = 512622
53 + 512569 = 512622
79 + 512543 = 512622
101 + 512521 = 512622

Showing the first eight; more decompositions exist.
