Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531026, here are decompositions:

3 + 531023 = 531026
37 + 530989 = 531026
43 + 530983 = 531026
79 + 530947 = 531026
157 + 530869 = 531026
193 + 530833 = 531026
229 + 530797 = 531026
283 + 530743 = 531026

Showing the first eight; more decompositions exist.
