Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531496, here are decompositions:

113 + 531383 = 531496
137 + 531359 = 531496
149 + 531347 = 531496
197 + 531299 = 531496
233 + 531263 = 531496
257 + 531239 = 531496
293 + 531203 = 531496
353 + 531143 = 531496

Showing the first eight; more decompositions exist.
