Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531526, here are decompositions:

5 + 531521 = 531526
29 + 531497 = 531526
167 + 531359 = 531526
173 + 531353 = 531526
179 + 531347 = 531526
227 + 531299 = 531526
239 + 531287 = 531526
263 + 531263 = 531526

Showing the first eight; more decompositions exist.
