Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531732, here are decompositions:

31 + 531701 = 531732
43 + 531689 = 531732
59 + 531673 = 531732
101 + 531631 = 531732
109 + 531623 = 531732
151 + 531581 = 531732
163 + 531569 = 531732
181 + 531551 = 531732

Showing the first eight; more decompositions exist.
