Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517724, here are decompositions:

3 + 517721 = 517724
7 + 517717 = 517724
13 + 517711 = 517724
127 + 517597 = 517724
211 + 517513 = 517724
223 + 517501 = 517724
307 + 517417 = 517724
313 + 517411 = 517724

Showing the first eight; more decompositions exist.
