Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530724, here are decompositions:

11 + 530713 = 530724
13 + 530711 = 530724
23 + 530701 = 530724
31 + 530693 = 530724
71 + 530653 = 530724
83 + 530641 = 530724
127 + 530597 = 530724
157 + 530567 = 530724

Showing the first eight; more decompositions exist.
