Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530218, here are decompositions:

41 + 530177 = 530218
89 + 530129 = 530218
131 + 530087 = 530218
167 + 530051 = 530218
191 + 530027 = 530218
197 + 530021 = 530218
239 + 529979 = 530218
257 + 529961 = 530218

Showing the first eight; more decompositions exist.
