Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 246, here are decompositions:

5 + 241 = 246
7 + 239 = 246
13 + 233 = 246
17 + 229 = 246
19 + 227 = 246
23 + 223 = 246
47 + 199 = 246
53 + 193 = 246

Showing the first eight; more decompositions exist.
