Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523864, here are decompositions:

17 + 523847 = 523864
71 + 523793 = 523864
101 + 523763 = 523864
191 + 523673 = 523864
197 + 523667 = 523864
227 + 523637 = 523864
233 + 523631 = 523864
293 + 523571 = 523864

Showing the first eight; more decompositions exist.
