Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531224, here are decompositions:

61 + 531163 = 531224
103 + 531121 = 531224
181 + 531043 = 531224
241 + 530983 = 531224
277 + 530947 = 531224
313 + 530911 = 531224
367 + 530857 = 531224
373 + 530851 = 531224

Showing the first eight; more decompositions exist.
