Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530928, here are decompositions:

17 + 530911 = 530928
31 + 530897 = 530928
59 + 530869 = 530928
67 + 530861 = 530928
71 + 530857 = 530928
131 + 530797 = 530928
197 + 530731 = 530928
227 + 530701 = 530928

Showing the first eight; more decompositions exist.
