Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531506, here are decompositions:

163 + 531343 = 531506
277 + 531229 = 531506
337 + 531169 = 531506
373 + 531133 = 531506
463 + 531043 = 531506
523 + 530983 = 531506
673 + 530833 = 531506
709 + 530797 = 531506

Showing the first eight; more decompositions exist.
