Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530726, here are decompositions:

13 + 530713 = 530726
67 + 530659 = 530726
73 + 530653 = 530726
127 + 530599 = 530726
193 + 530533 = 530726
199 + 530527 = 530726
283 + 530443 = 530726
337 + 530389 = 530726

Showing the first eight; more decompositions exist.
