Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31308, here are decompositions:

31 + 31277 = 31308
37 + 31271 = 31308
41 + 31267 = 31308
59 + 31249 = 31308
61 + 31247 = 31308
71 + 31237 = 31308
89 + 31219 = 31308
127 + 31181 = 31308

Showing the first eight; more decompositions exist.
