Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531196, here are decompositions:

23 + 531173 = 531196
53 + 531143 = 531196
173 + 531023 = 531196
179 + 531017 = 531196
227 + 530969 = 531196
353 + 530843 = 531196
359 + 530837 = 531196
389 + 530807 = 531196

Showing the first eight; more decompositions exist.
