Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530920, here are decompositions:

23 + 530897 = 530920
59 + 530861 = 530920
83 + 530837 = 530920
113 + 530807 = 530920
167 + 530753 = 530920
179 + 530741 = 530920
227 + 530693 = 530920
251 + 530669 = 530920

Showing the first eight; more decompositions exist.
