Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511724, here are decompositions:

13 + 511711 = 511724
97 + 511627 = 511724
151 + 511573 = 511724
271 + 511453 = 511724
277 + 511447 = 511724
307 + 511417 = 511724
337 + 511387 = 511724
373 + 511351 = 511724

Showing the first eight; more decompositions exist.
