Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31340, here are decompositions:

3 + 31337 = 31340
7 + 31333 = 31340
13 + 31327 = 31340
19 + 31321 = 31340
73 + 31267 = 31340
103 + 31237 = 31340
109 + 31231 = 31340
151 + 31189 = 31340

Showing the first eight; more decompositions exist.
