Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511936, here are decompositions:

3 + 511933 = 511936
149 + 511787 = 511936
179 + 511757 = 511936
233 + 511703 = 511936
353 + 511583 = 511936
449 + 511487 = 511936
479 + 511457 = 511936
599 + 511337 = 511936

Showing the first eight; more decompositions exist.
