Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531932, here are decompositions:

13 + 531919 = 531932
31 + 531901 = 531932
61 + 531871 = 531932
109 + 531823 = 531932
139 + 531793 = 531932
601 + 531331 = 531932
769 + 531163 = 531932
811 + 531121 = 531932

Showing the first eight; more decompositions exist.
