Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31342, here are decompositions:

5 + 31337 = 31342
23 + 31319 = 31342
71 + 31271 = 31342
83 + 31259 = 31342
89 + 31253 = 31342
149 + 31193 = 31342
191 + 31151 = 31342
251 + 31091 = 31342

Showing the first eight; more decompositions exist.
