Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2248, here are decompositions:

5 + 2243 = 2248
11 + 2237 = 2248
41 + 2207 = 2248
107 + 2141 = 2248
137 + 2111 = 2248
149 + 2099 = 2248
167 + 2081 = 2248
179 + 2069 = 2248

Showing the first eight; more decompositions exist.
