Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13858, here are decompositions:

17 + 13841 = 13858
29 + 13829 = 13858
59 + 13799 = 13858
101 + 13757 = 13858
107 + 13751 = 13858
137 + 13721 = 13858
149 + 13709 = 13858
167 + 13691 = 13858

Showing the first eight; more decompositions exist.
