Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531982, here are decompositions:

5 + 531977 = 531982
71 + 531911 = 531982
149 + 531833 = 531982
251 + 531731 = 531982
281 + 531701 = 531982
293 + 531689 = 531982
359 + 531623 = 531982
401 + 531581 = 531982

Showing the first eight; more decompositions exist.
