Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38428, here are decompositions:

101 + 38327 = 38428
107 + 38321 = 38428
167 + 38261 = 38428
191 + 38237 = 38428
197 + 38231 = 38428
227 + 38201 = 38428
239 + 38189 = 38428
251 + 38177 = 38428

Showing the first eight; more decompositions exist.
