Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511984, here are decompositions:

23 + 511961 = 511984
173 + 511811 = 511984
191 + 511793 = 511984
197 + 511787 = 511984
227 + 511757 = 511984
281 + 511703 = 511984
293 + 511691 = 511984
353 + 511631 = 511984

Showing the first eight; more decompositions exist.
