Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517722, here are decompositions:

5 + 517717 = 517722
11 + 517711 = 517722
83 + 517639 = 517722
103 + 517619 = 517722
109 + 517613 = 517722
113 + 517609 = 517722
151 + 517571 = 517722
173 + 517549 = 517722

Showing the first eight; more decompositions exist.
