Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530668, here are decompositions:

59 + 530609 = 530668
71 + 530597 = 530668
101 + 530567 = 530668
137 + 530531 = 530668
167 + 530501 = 530668
239 + 530429 = 530668
389 + 530279 = 530668
401 + 530267 = 530668

Showing the first eight; more decompositions exist.
