Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512718, here are decompositions:

5 + 512713 = 512718
7 + 512711 = 512718
47 + 512671 = 512718
61 + 512657 = 512718
97 + 512621 = 512718
109 + 512609 = 512718
127 + 512591 = 512718
137 + 512581 = 512718

Showing the first eight; more decompositions exist.
