Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 354, here are decompositions:

5 + 349 = 354
7 + 347 = 354
17 + 337 = 354
23 + 331 = 354
37 + 317 = 354
41 + 313 = 354
43 + 311 = 354
47 + 307 = 354

Showing the first eight; more decompositions exist.
