Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38638, here are decompositions:

29 + 38609 = 38638
71 + 38567 = 38638
137 + 38501 = 38638
179 + 38459 = 38638
191 + 38447 = 38638
311 + 38327 = 38638
317 + 38321 = 38638
401 + 38237 = 38638

Showing the first eight; more decompositions exist.
