Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531832, here are decompositions:

5 + 531827 = 531832
11 + 531821 = 531832
101 + 531731 = 531832
131 + 531701 = 531832
251 + 531581 = 531832
263 + 531569 = 531832
281 + 531551 = 531832
311 + 531521 = 531832

Showing the first eight; more decompositions exist.
