Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 350, here are decompositions:

3 + 347 = 350
13 + 337 = 350
19 + 331 = 350
37 + 313 = 350
43 + 307 = 350
67 + 283 = 350
73 + 277 = 350
79 + 271 = 350

Showing the first eight; more decompositions exist.
