Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38668, here are decompositions:

17 + 38651 = 38668
29 + 38639 = 38668
59 + 38609 = 38668
101 + 38567 = 38668
107 + 38561 = 38668
167 + 38501 = 38668
317 + 38351 = 38668
347 + 38321 = 38668

Showing the first eight; more decompositions exist.
