Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530238, here are decompositions:

11 + 530227 = 530238
29 + 530209 = 530238
41 + 530197 = 530238
61 + 530177 = 530238
101 + 530137 = 530238
109 + 530129 = 530238
151 + 530087 = 530238
197 + 530041 = 530238

Showing the first eight; more decompositions exist.
