Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517748, here are decompositions:

19 + 517729 = 517748
31 + 517717 = 517748
37 + 517711 = 517748
109 + 517639 = 517748
139 + 517609 = 517748
151 + 517597 = 517748
199 + 517549 = 517748
241 + 517507 = 517748

Showing the first eight; more decompositions exist.
