Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13900, here are decompositions:

17 + 13883 = 13900
23 + 13877 = 13900
41 + 13859 = 13900
59 + 13841 = 13900
71 + 13829 = 13900
101 + 13799 = 13900
137 + 13763 = 13900
149 + 13751 = 13900

Showing the first eight; more decompositions exist.
