Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530626, here are decompositions:

17 + 530609 = 530626
23 + 530603 = 530626
29 + 530597 = 530626
59 + 530567 = 530626
113 + 530513 = 530626
179 + 530447 = 530626
197 + 530429 = 530626
233 + 530393 = 530626

Showing the first eight; more decompositions exist.
