Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531332, here are decompositions:

79 + 531253 = 531332
103 + 531229 = 531332
163 + 531169 = 531332
199 + 531133 = 531332
211 + 531121 = 531332
229 + 531103 = 531332
349 + 530983 = 531332
421 + 530911 = 531332

Showing the first eight; more decompositions exist.
