Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531214, here are decompositions:

11 + 531203 = 531214
17 + 531197 = 531214
41 + 531173 = 531214
71 + 531143 = 531214
113 + 531101 = 531214
191 + 531023 = 531214
197 + 531017 = 531214
317 + 530897 = 531214

Showing the first eight; more decompositions exist.
