Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13870, here are decompositions:

11 + 13859 = 13870
29 + 13841 = 13870
41 + 13829 = 13870
71 + 13799 = 13870
89 + 13781 = 13870
107 + 13763 = 13870
113 + 13757 = 13870
149 + 13721 = 13870

Showing the first eight; more decompositions exist.
