Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512644, here are decompositions:

3 + 512641 = 512644
23 + 512621 = 512644
47 + 512597 = 512644
53 + 512591 = 512644
71 + 512573 = 512644
101 + 512543 = 512644
107 + 512537 = 512644
113 + 512531 = 512644

Showing the first eight; more decompositions exist.
