Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531512, here are decompositions:

31 + 531481 = 531512
181 + 531331 = 531512
283 + 531229 = 531512
349 + 531163 = 531512
379 + 531133 = 531512
409 + 531103 = 531512
433 + 531079 = 531512
523 + 530989 = 531512

Showing the first eight; more decompositions exist.
