Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517806, here are decompositions:

59 + 517747 = 517806
67 + 517739 = 517806
73 + 517733 = 517806
89 + 517717 = 517806
167 + 517639 = 517806
193 + 517613 = 517806
197 + 517609 = 517806
229 + 517577 = 517806

Showing the first eight; more decompositions exist.
