Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531054, here are decompositions:

11 + 531043 = 531054
31 + 531023 = 531054
37 + 531017 = 531054
71 + 530983 = 531054
107 + 530947 = 531054
157 + 530897 = 531054
193 + 530861 = 531054
197 + 530857 = 531054

Showing the first eight; more decompositions exist.
