Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517728, here are decompositions:

7 + 517721 = 517728
11 + 517717 = 517728
17 + 517711 = 517728
89 + 517639 = 517728
109 + 517619 = 517728
131 + 517597 = 517728
139 + 517589 = 517728
151 + 517577 = 517728

Showing the first eight; more decompositions exist.
