Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512650, here are decompositions:

29 + 512621 = 512650
41 + 512609 = 512650
53 + 512597 = 512650
59 + 512591 = 512650
71 + 512579 = 512650
107 + 512543 = 512650
113 + 512537 = 512650
317 + 512333 = 512650

Showing the first eight; more decompositions exist.
