Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 274, here are decompositions:

3 + 271 = 274
5 + 269 = 274
11 + 263 = 274
17 + 257 = 274
23 + 251 = 274
41 + 233 = 274
47 + 227 = 274
83 + 191 = 274

Showing the first eight; more decompositions exist.
