Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530538, here are decompositions:

5 + 530533 = 530538
7 + 530531 = 530538
11 + 530527 = 530538
31 + 530507 = 530538
37 + 530501 = 530538
109 + 530429 = 530538
137 + 530401 = 530538
149 + 530389 = 530538

Showing the first eight; more decompositions exist.
