Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538528, here are decompositions:

5 + 538523 = 538528
17 + 538511 = 538528
41 + 538487 = 538528
47 + 538481 = 538528
71 + 538457 = 538528
131 + 538397 = 538528
197 + 538331 = 538528
227 + 538301 = 538528

Showing the first eight; more decompositions exist.
