Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511744, here are decompositions:

41 + 511703 = 511744
53 + 511691 = 511744
113 + 511631 = 511744
257 + 511487 = 511744
281 + 511463 = 511744
353 + 511391 = 511744
383 + 511361 = 511744
521 + 511223 = 511744

Showing the first eight; more decompositions exist.
