Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531294, here are decompositions:

7 + 531287 = 531294
13 + 531281 = 531294
31 + 531263 = 531294
41 + 531253 = 531294
97 + 531197 = 531294
131 + 531163 = 531294
151 + 531143 = 531294
173 + 531121 = 531294

Showing the first eight; more decompositions exist.
