Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531344, here are decompositions:

7 + 531337 = 531344
13 + 531331 = 531344
181 + 531163 = 531344
211 + 531133 = 531344
223 + 531121 = 531344
241 + 531103 = 531344
367 + 530977 = 531344
397 + 530947 = 531344

Showing the first eight; more decompositions exist.
