Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517664, here are decompositions:

61 + 517603 = 517664
67 + 517597 = 517664
151 + 517513 = 517664
157 + 517507 = 517664
163 + 517501 = 517664
193 + 517471 = 517664
271 + 517393 = 517664
283 + 517381 = 517664

Showing the first eight; more decompositions exist.
