Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530738, here are decompositions:

7 + 530731 = 530738
37 + 530701 = 530738
79 + 530659 = 530738
97 + 530641 = 530738
139 + 530599 = 530738
199 + 530539 = 530738
211 + 530527 = 530738
337 + 530401 = 530738

Showing the first eight; more decompositions exist.
