Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531028, here are decompositions:

5 + 531023 = 531028
11 + 531017 = 531028
59 + 530969 = 531028
131 + 530897 = 531028
167 + 530861 = 531028
191 + 530837 = 531028
317 + 530711 = 531028
359 + 530669 = 531028

Showing the first eight; more decompositions exist.
