Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13838, here are decompositions:

7 + 13831 = 13838
31 + 13807 = 13838
79 + 13759 = 13838
109 + 13729 = 13838
127 + 13711 = 13838
151 + 13687 = 13838
157 + 13681 = 13838
211 + 13627 = 13838

Showing the first eight; more decompositions exist.
