Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13898, here are decompositions:

19 + 13879 = 13898
67 + 13831 = 13898
109 + 13789 = 13898
139 + 13759 = 13898
211 + 13687 = 13898
229 + 13669 = 13898
271 + 13627 = 13898
307 + 13591 = 13898

Showing the first eight; more decompositions exist.
