Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13880, here are decompositions:

3 + 13877 = 13880
7 + 13873 = 13880
73 + 13807 = 13880
151 + 13729 = 13880
157 + 13723 = 13880
193 + 13687 = 13880
199 + 13681 = 13880
211 + 13669 = 13880

Showing the first eight; more decompositions exist.
