Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530408, here are decompositions:

7 + 530401 = 530408
19 + 530389 = 530408
79 + 530329 = 530408
157 + 530251 = 530408
181 + 530227 = 530408
199 + 530209 = 530408
211 + 530197 = 530408
271 + 530137 = 530408

Showing the first eight; more decompositions exist.
