Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512626, here are decompositions:

5 + 512621 = 512626
17 + 512609 = 512626
29 + 512597 = 512626
47 + 512579 = 512626
53 + 512573 = 512626
83 + 512543 = 512626
89 + 512537 = 512626
197 + 512429 = 512626

Showing the first eight; more decompositions exist.
