Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38938, here are decompositions:

5 + 38933 = 38938
17 + 38921 = 38938
47 + 38891 = 38938
71 + 38867 = 38938
191 + 38747 = 38938
227 + 38711 = 38938
239 + 38699 = 38938
269 + 38669 = 38938

Showing the first eight; more decompositions exist.
