Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530516, here are decompositions:

3 + 530513 = 530516
73 + 530443 = 530516
127 + 530389 = 530516
157 + 530359 = 530516
163 + 530353 = 530516
223 + 530293 = 530516
307 + 530209 = 530516
313 + 530203 = 530516

Showing the first eight; more decompositions exist.
