Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 358, here are decompositions:

5 + 353 = 358
11 + 347 = 358
41 + 317 = 358
47 + 311 = 358
89 + 269 = 358
101 + 257 = 358
107 + 251 = 358
131 + 227 = 358

Showing the first eight; more decompositions exist.
