Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530628, here are decompositions:

19 + 530609 = 530628
29 + 530599 = 530628
31 + 530597 = 530628
61 + 530567 = 530628
79 + 530549 = 530628
89 + 530539 = 530628
97 + 530531 = 530628
101 + 530527 = 530628

Showing the first eight; more decompositions exist.
