Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531070, here are decompositions:

47 + 531023 = 531070
53 + 531017 = 531070
101 + 530969 = 531070
173 + 530897 = 531070
227 + 530843 = 531070
233 + 530837 = 531070
263 + 530807 = 531070
317 + 530753 = 531070

Showing the first eight; more decompositions exist.
