Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38818, here are decompositions:

71 + 38747 = 38818
89 + 38729 = 38818
107 + 38711 = 38818
149 + 38669 = 38818
167 + 38651 = 38818
179 + 38639 = 38818
251 + 38567 = 38818
257 + 38561 = 38818

Showing the first eight; more decompositions exist.
