Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523810, here are decompositions:

17 + 523793 = 523810
47 + 523763 = 523810
137 + 523673 = 523810
173 + 523637 = 523810
179 + 523631 = 523810
233 + 523577 = 523810
239 + 523571 = 523810
257 + 523553 = 523810

Showing the first eight; more decompositions exist.
