Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531132, here are decompositions:

11 + 531121 = 531132
29 + 531103 = 531132
31 + 531101 = 531132
53 + 531079 = 531132
61 + 531071 = 531132
89 + 531043 = 531132
109 + 531023 = 531132
149 + 530983 = 531132

Showing the first eight; more decompositions exist.
