Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517782, here are decompositions:

43 + 517739 = 517782
53 + 517729 = 517782
61 + 517721 = 517782
71 + 517711 = 517782
163 + 517619 = 517782
173 + 517609 = 517782
179 + 517603 = 517782
193 + 517589 = 517782

Showing the first eight; more decompositions exist.
