Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38838, here are decompositions:

5 + 38833 = 38838
17 + 38821 = 38838
47 + 38791 = 38838
71 + 38767 = 38838
89 + 38749 = 38838
101 + 38737 = 38838
109 + 38729 = 38838
127 + 38711 = 38838

Showing the first eight; more decompositions exist.
