Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2206, here are decompositions:

3 + 2203 = 2206
53 + 2153 = 2206
107 + 2099 = 2206
137 + 2069 = 2206
167 + 2039 = 2206
179 + 2027 = 2206
227 + 1979 = 2206
233 + 1973 = 2206

Showing the first eight; more decompositions exist.
