Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520864, here are decompositions:

11 + 520853 = 520864
23 + 520841 = 520864
101 + 520763 = 520864
173 + 520691 = 520864
233 + 520631 = 520864
257 + 520607 = 520864
293 + 520571 = 520864
317 + 520547 = 520864

Showing the first eight; more decompositions exist.
