Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531270, here are decompositions:

7 + 531263 = 531270
17 + 531253 = 531270
31 + 531239 = 531270
41 + 531229 = 531270
67 + 531203 = 531270
73 + 531197 = 531270
97 + 531173 = 531270
101 + 531169 = 531270

Showing the first eight; more decompositions exist.
