Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523866, here are decompositions:

19 + 523847 = 523866
37 + 523829 = 523866
73 + 523793 = 523866
89 + 523777 = 523866
103 + 523763 = 523866
107 + 523759 = 523866
137 + 523729 = 523866
149 + 523717 = 523866

Showing the first eight; more decompositions exist.
