Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2216, here are decompositions:

3 + 2213 = 2216
13 + 2203 = 2216
37 + 2179 = 2216
73 + 2143 = 2216
79 + 2137 = 2216
103 + 2113 = 2216
127 + 2089 = 2216
163 + 2053 = 2216

Showing the first eight; more decompositions exist.
