Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523966, here are decompositions:

17 + 523949 = 523966
29 + 523937 = 523966
59 + 523907 = 523966
89 + 523877 = 523966
137 + 523829 = 523966
173 + 523793 = 523966
293 + 523673 = 523966
389 + 523577 = 523966

Showing the first eight; more decompositions exist.
