Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530730, here are decompositions:

17 + 530713 = 530730
19 + 530711 = 530730
29 + 530701 = 530730
37 + 530693 = 530730
61 + 530669 = 530730
71 + 530659 = 530730
89 + 530641 = 530730
127 + 530603 = 530730

Showing the first eight; more decompositions exist.
