Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530540, here are decompositions:

7 + 530533 = 530540
13 + 530527 = 530540
97 + 530443 = 530540
139 + 530401 = 530540
151 + 530389 = 530540
181 + 530359 = 530540
211 + 530329 = 530540
313 + 530227 = 530540

Showing the first eight; more decompositions exist.
