Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531124, here are decompositions:

3 + 531121 = 531124
23 + 531101 = 531124
53 + 531071 = 531124
101 + 531023 = 531124
107 + 531017 = 531124
227 + 530897 = 531124
263 + 530861 = 531124
281 + 530843 = 531124

Showing the first eight; more decompositions exist.
