Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531724, here are decompositions:

23 + 531701 = 531724
101 + 531623 = 531724
113 + 531611 = 531724
173 + 531551 = 531724
227 + 531497 = 531724
443 + 531281 = 531724
461 + 531263 = 531724
521 + 531203 = 531724

Showing the first eight; more decompositions exist.
