Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531292, here are decompositions:

5 + 531287 = 531292
11 + 531281 = 531292
29 + 531263 = 531292
53 + 531239 = 531292
89 + 531203 = 531292
149 + 531143 = 531292
191 + 531101 = 531292
269 + 531023 = 531292

Showing the first eight; more decompositions exist.
