Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531914, here are decompositions:

3 + 531911 = 531914
13 + 531901 = 531914
37 + 531877 = 531914
43 + 531871 = 531914
67 + 531847 = 531914
73 + 531841 = 531914
241 + 531673 = 531914
277 + 531637 = 531914

Showing the first eight; more decompositions exist.
