Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454, here are decompositions:

61 + 31393 = 31454
67 + 31387 = 31454
97 + 31357 = 31454
127 + 31327 = 31454
223 + 31231 = 31454
271 + 31183 = 31454
277 + 31177 = 31454
307 + 31147 = 31454

Showing the first eight; more decompositions exist.
