Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523806, here are decompositions:

5 + 523801 = 523806
13 + 523793 = 523806
29 + 523777 = 523806
43 + 523763 = 523806
47 + 523759 = 523806
89 + 523717 = 523806
137 + 523669 = 523806
139 + 523667 = 523806

Showing the first eight; more decompositions exist.
