Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531136, here are decompositions:

3 + 531133 = 531136
113 + 531023 = 531136
167 + 530969 = 531136
239 + 530897 = 531136
293 + 530843 = 531136
383 + 530753 = 531136
443 + 530693 = 531136
467 + 530669 = 531136

Showing the first eight; more decompositions exist.
