Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2236, here are decompositions:

23 + 2213 = 2236
29 + 2207 = 2236
83 + 2153 = 2236
107 + 2129 = 2236
137 + 2099 = 2236
149 + 2087 = 2236
167 + 2069 = 2236
173 + 2063 = 2236

Showing the first eight; more decompositions exist.
