Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31406, here are decompositions:

13 + 31393 = 31406
19 + 31387 = 31406
73 + 31333 = 31406
79 + 31327 = 31406
139 + 31267 = 31406
157 + 31249 = 31406
223 + 31183 = 31406
229 + 31177 = 31406

Showing the first eight; more decompositions exist.
