Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538216, here are decompositions:

17 + 538199 = 538216
53 + 538163 = 538216
59 + 538157 = 538216
89 + 538127 = 538216
137 + 538079 = 538216
167 + 538049 = 538216
197 + 538019 = 538216
317 + 537899 = 538216

Showing the first eight; more decompositions exist.
