Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531316, here are decompositions:

17 + 531299 = 531316
29 + 531287 = 531316
53 + 531263 = 531316
113 + 531203 = 531316
173 + 531143 = 531316
293 + 531023 = 531316
347 + 530969 = 531316
419 + 530897 = 531316

Showing the first eight; more decompositions exist.
