Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531936, here are decompositions:

17 + 531919 = 531936
59 + 531877 = 531936
73 + 531863 = 531936
79 + 531857 = 531936
89 + 531847 = 531936
103 + 531833 = 531936
109 + 531827 = 531936
113 + 531823 = 531936

Showing the first eight; more decompositions exist.
