Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531330, here are decompositions:

31 + 531299 = 531330
43 + 531287 = 531330
67 + 531263 = 531330
101 + 531229 = 531330
127 + 531203 = 531330
157 + 531173 = 531330
167 + 531163 = 531330
197 + 531133 = 531330

Showing the first eight; more decompositions exist.
