Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31378, here are decompositions:

41 + 31337 = 31378
59 + 31319 = 31378
71 + 31307 = 31378
101 + 31277 = 31378
107 + 31271 = 31378
131 + 31247 = 31378
197 + 31181 = 31378
227 + 31151 = 31378

Showing the first eight; more decompositions exist.
