Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530450, here are decompositions:

3 + 530447 = 530450
7 + 530443 = 530450
61 + 530389 = 530450
97 + 530353 = 530450
157 + 530293 = 530450
199 + 530251 = 530450
223 + 530227 = 530450
241 + 530209 = 530450

Showing the first eight; more decompositions exist.
