Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531076, here are decompositions:

5 + 531071 = 531076
53 + 531023 = 531076
59 + 531017 = 531076
107 + 530969 = 531076
179 + 530897 = 531076
233 + 530843 = 531076
239 + 530837 = 531076
269 + 530807 = 531076

Showing the first eight; more decompositions exist.
