Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530028, here are decompositions:

7 + 530021 = 530028
11 + 530017 = 530028
29 + 529999 = 530028
41 + 529987 = 530028
47 + 529981 = 530028
67 + 529961 = 530028
71 + 529957 = 530028
89 + 529939 = 530028

Showing the first eight; more decompositions exist.
