Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31374, here are decompositions:

17 + 31357 = 31374
37 + 31337 = 31374
41 + 31333 = 31374
47 + 31327 = 31374
53 + 31321 = 31374
67 + 31307 = 31374
97 + 31277 = 31374
103 + 31271 = 31374

Showing the first eight; more decompositions exist.
