Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2230, here are decompositions:

17 + 2213 = 2230
23 + 2207 = 2230
89 + 2141 = 2230
101 + 2129 = 2230
131 + 2099 = 2230
149 + 2081 = 2230
167 + 2063 = 2230
191 + 2039 = 2230

Showing the first eight; more decompositions exist.
