Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2268, here are decompositions:

17 + 2251 = 2268
29 + 2239 = 2268
31 + 2237 = 2268
47 + 2221 = 2268
61 + 2207 = 2268
89 + 2179 = 2268
107 + 2161 = 2268
127 + 2141 = 2268

Showing the first eight; more decompositions exist.
