Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530806, here are decompositions:

53 + 530753 = 530806
113 + 530693 = 530806
137 + 530669 = 530806
197 + 530609 = 530806
239 + 530567 = 530806
257 + 530549 = 530806
293 + 530513 = 530806
359 + 530447 = 530806

Showing the first eight; more decompositions exist.
