Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31344, here are decompositions:

7 + 31337 = 31344
11 + 31333 = 31344
17 + 31327 = 31344
23 + 31321 = 31344
37 + 31307 = 31344
67 + 31277 = 31344
73 + 31271 = 31344
97 + 31247 = 31344

Showing the first eight; more decompositions exist.
