Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531088, here are decompositions:

17 + 531071 = 531088
71 + 531017 = 531088
191 + 530897 = 531088
227 + 530861 = 531088
251 + 530837 = 531088
281 + 530807 = 531088
347 + 530741 = 531088
419 + 530669 = 531088

Showing the first eight; more decompositions exist.
