Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531492, here are decompositions:

11 + 531481 = 531492
109 + 531383 = 531492
139 + 531353 = 531492
149 + 531343 = 531492
193 + 531299 = 531492
211 + 531281 = 531492
229 + 531263 = 531492
239 + 531253 = 531492

Showing the first eight; more decompositions exist.
