Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531474, here are decompositions:

17 + 531457 = 531474
127 + 531347 = 531474
131 + 531343 = 531474
137 + 531337 = 531474
193 + 531281 = 531474
211 + 531263 = 531474
271 + 531203 = 531474
277 + 531197 = 531474

Showing the first eight; more decompositions exist.
