Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538284, here are decompositions:

17 + 538267 = 538284
37 + 538247 = 538284
83 + 538201 = 538284
127 + 538157 = 538284
137 + 538147 = 538284
157 + 538127 = 538284
163 + 538121 = 538284
167 + 538117 = 538284

Showing the first eight; more decompositions exist.
