Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38728, here are decompositions:

5 + 38723 = 38728
17 + 38711 = 38728
29 + 38699 = 38728
59 + 38669 = 38728
89 + 38639 = 38728
167 + 38561 = 38728
227 + 38501 = 38728
269 + 38459 = 38728

Showing the first eight; more decompositions exist.
