Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531046, here are decompositions:

3 + 531043 = 531046
23 + 531023 = 531046
29 + 531017 = 531046
149 + 530897 = 531046
239 + 530807 = 531046
293 + 530753 = 531046
353 + 530693 = 531046
443 + 530603 = 531046

Showing the first eight; more decompositions exist.
