Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531066, here are decompositions:

23 + 531043 = 531066
43 + 531023 = 531066
83 + 530983 = 531066
89 + 530977 = 531066
97 + 530969 = 531066
197 + 530869 = 531066
223 + 530843 = 531066
229 + 530837 = 531066

Showing the first eight; more decompositions exist.
