Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 344, here are decompositions:

7 + 337 = 344
13 + 331 = 344
31 + 313 = 344
37 + 307 = 344
61 + 283 = 344
67 + 277 = 344
73 + 271 = 344
103 + 241 = 344

Showing the first eight; more decompositions exist.
