Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531262, here are decompositions:

23 + 531239 = 531262
59 + 531203 = 531262
89 + 531173 = 531262
191 + 531071 = 531262
239 + 531023 = 531262
293 + 530969 = 531262
401 + 530861 = 531262
419 + 530843 = 531262

Showing the first eight; more decompositions exist.
