Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530390, here are decompositions:

31 + 530359 = 530390
37 + 530353 = 530390
61 + 530329 = 530390
97 + 530293 = 530390
139 + 530251 = 530390
163 + 530227 = 530390
181 + 530209 = 530390
193 + 530197 = 530390

Showing the first eight; more decompositions exist.
