Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13966, here are decompositions:

3 + 13963 = 13966
53 + 13913 = 13966
59 + 13907 = 13966
83 + 13883 = 13966
89 + 13877 = 13966
107 + 13859 = 13966
137 + 13829 = 13966
167 + 13799 = 13966

Showing the first eight; more decompositions exist.
