Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531268, here are decompositions:

5 + 531263 = 531268
29 + 531239 = 531268
71 + 531197 = 531268
167 + 531101 = 531268
197 + 531071 = 531268
251 + 531017 = 531268
431 + 530837 = 531268
461 + 530807 = 531268

Showing the first eight; more decompositions exist.
