Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31356, here are decompositions:

19 + 31337 = 31356
23 + 31333 = 31356
29 + 31327 = 31356
37 + 31319 = 31356
79 + 31277 = 31356
89 + 31267 = 31356
97 + 31259 = 31356
103 + 31253 = 31356

Showing the first eight; more decompositions exist.
