Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523900, here are decompositions:

23 + 523877 = 523900
53 + 523847 = 523900
71 + 523829 = 523900
107 + 523793 = 523900
137 + 523763 = 523900
227 + 523673 = 523900
233 + 523667 = 523900
263 + 523637 = 523900

Showing the first eight; more decompositions exist.
