Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523870, here are decompositions:

3 + 523867 = 523870
23 + 523847 = 523870
41 + 523829 = 523870
107 + 523763 = 523870
197 + 523673 = 523870
233 + 523637 = 523870
239 + 523631 = 523870
293 + 523577 = 523870

Showing the first eight; more decompositions exist.
