Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511568, here are decompositions:

19 + 511549 = 511568
61 + 511507 = 511568
151 + 511417 = 511568
181 + 511387 = 511568
241 + 511327 = 511568
271 + 511297 = 511568
307 + 511261 = 511568
331 + 511237 = 511568

Showing the first eight; more decompositions exist.
