Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13906, here are decompositions:

3 + 13903 = 13906
5 + 13901 = 13906
23 + 13883 = 13906
29 + 13877 = 13906
47 + 13859 = 13906
107 + 13799 = 13906
149 + 13757 = 13906
197 + 13709 = 13906

Showing the first eight; more decompositions exist.
