Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517740, here are decompositions:

7 + 517733 = 517740
11 + 517729 = 517740
19 + 517721 = 517740
23 + 517717 = 517740
29 + 517711 = 517740
101 + 517639 = 517740
103 + 517637 = 517740
127 + 517613 = 517740

Showing the first eight; more decompositions exist.
