Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511856, here are decompositions:

13 + 511843 = 511856
223 + 511633 = 511856
229 + 511627 = 511856
277 + 511579 = 511856
283 + 511573 = 511856
307 + 511549 = 511856
337 + 511519 = 511856
349 + 511507 = 511856

Showing the first eight; more decompositions exist.
