Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517790, here are decompositions:

43 + 517747 = 517790
61 + 517729 = 517790
73 + 517717 = 517790
79 + 517711 = 517790
151 + 517639 = 517790
181 + 517609 = 517790
193 + 517597 = 517790
241 + 517549 = 517790

Showing the first eight; more decompositions exist.
