Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531074, here are decompositions:

3 + 531071 = 531074
31 + 531043 = 531074
97 + 530977 = 531074
127 + 530947 = 531074
163 + 530911 = 531074
223 + 530851 = 531074
241 + 530833 = 531074
277 + 530797 = 531074

Showing the first eight; more decompositions exist.
