Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511864, here are decompositions:

5 + 511859 = 511864
53 + 511811 = 511864
71 + 511793 = 511864
107 + 511757 = 511864
173 + 511691 = 511864
233 + 511631 = 511864
281 + 511583 = 511864
401 + 511463 = 511864

Showing the first eight; more decompositions exist.
