Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531836, here are decompositions:

3 + 531833 = 531836
13 + 531823 = 531836
37 + 531799 = 531836
43 + 531793 = 531836
163 + 531673 = 531836
199 + 531637 = 531836
223 + 531613 = 531836
379 + 531457 = 531836

Showing the first eight; more decompositions exist.
