Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2266, here are decompositions:

23 + 2243 = 2266
29 + 2237 = 2266
53 + 2213 = 2266
59 + 2207 = 2266
113 + 2153 = 2266
137 + 2129 = 2266
167 + 2099 = 2266
179 + 2087 = 2266

Showing the first eight; more decompositions exist.
