Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530820, here are decompositions:

13 + 530807 = 530820
23 + 530797 = 530820
47 + 530773 = 530820
53 + 530767 = 530820
67 + 530753 = 530820
79 + 530741 = 530820
89 + 530731 = 530820
107 + 530713 = 530820

Showing the first eight; more decompositions exist.
