Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511768, here are decompositions:

11 + 511757 = 511768
137 + 511631 = 511768
227 + 511541 = 511768
281 + 511487 = 511768
311 + 511457 = 511768
359 + 511409 = 511768
431 + 511337 = 511768
479 + 511289 = 511768

Showing the first eight; more decompositions exist.
