Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531264, here are decompositions:

11 + 531253 = 531264
61 + 531203 = 531264
67 + 531197 = 531264
101 + 531163 = 531264
131 + 531133 = 531264
163 + 531101 = 531264
193 + 531071 = 531264
241 + 531023 = 531264

Showing the first eight; more decompositions exist.
