Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531716, here are decompositions:

43 + 531673 = 531716
79 + 531637 = 531716
103 + 531613 = 531716
127 + 531589 = 531716
373 + 531343 = 531716
379 + 531337 = 531716
463 + 531253 = 531716
487 + 531229 = 531716

Showing the first eight; more decompositions exist.
