Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2288, here are decompositions:

7 + 2281 = 2288
19 + 2269 = 2288
37 + 2251 = 2288
67 + 2221 = 2288
109 + 2179 = 2288
127 + 2161 = 2288
151 + 2137 = 2288
157 + 2131 = 2288

Showing the first eight; more decompositions exist.
