Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531460, here are decompositions:

3 + 531457 = 531460
101 + 531359 = 531460
107 + 531353 = 531460
113 + 531347 = 531460
173 + 531287 = 531460
179 + 531281 = 531460
197 + 531263 = 531460
257 + 531203 = 531460

Showing the first eight; more decompositions exist.
