Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31274, here are decompositions:

3 + 31271 = 31274
7 + 31267 = 31274
37 + 31237 = 31274
43 + 31231 = 31274
97 + 31177 = 31274
127 + 31147 = 31274
151 + 31123 = 31274
193 + 31081 = 31274

Showing the first eight; more decompositions exist.
