Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31394, here are decompositions:

3 + 31391 = 31394
7 + 31387 = 31394
37 + 31357 = 31394
61 + 31333 = 31394
67 + 31327 = 31394
73 + 31321 = 31394
127 + 31267 = 31394
157 + 31237 = 31394

Showing the first eight; more decompositions exist.
