Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531466, here are decompositions:

83 + 531383 = 531466
107 + 531359 = 531466
113 + 531353 = 531466
167 + 531299 = 531466
179 + 531287 = 531466
227 + 531239 = 531466
263 + 531203 = 531466
269 + 531197 = 531466

Showing the first eight; more decompositions exist.
