Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512668, here are decompositions:

5 + 512663 = 512668
11 + 512657 = 512668
47 + 512621 = 512668
59 + 512609 = 512668
71 + 512597 = 512668
89 + 512579 = 512668
131 + 512537 = 512668
137 + 512531 = 512668

Showing the first eight; more decompositions exist.
