Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31338, here are decompositions:

5 + 31333 = 31338
11 + 31327 = 31338
17 + 31321 = 31338
19 + 31319 = 31338
31 + 31307 = 31338
61 + 31277 = 31338
67 + 31271 = 31338
71 + 31267 = 31338

Showing the first eight; more decompositions exist.
