Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531940, here are decompositions:

29 + 531911 = 531940
83 + 531857 = 531940
107 + 531833 = 531940
113 + 531827 = 531940
239 + 531701 = 531940
251 + 531689 = 531940
317 + 531623 = 531940
359 + 531581 = 531940

Showing the first eight; more decompositions exist.
