Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538258, here are decompositions:

11 + 538247 = 538258
59 + 538199 = 538258
101 + 538157 = 538258
107 + 538151 = 538258
131 + 538127 = 538258
137 + 538121 = 538258
179 + 538079 = 538258
239 + 538019 = 538258

Showing the first eight; more decompositions exist.
