Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2272, here are decompositions:

3 + 2269 = 2272
5 + 2267 = 2272
29 + 2243 = 2272
59 + 2213 = 2272
131 + 2141 = 2272
173 + 2099 = 2272
191 + 2081 = 2272
233 + 2039 = 2272

Showing the first eight; more decompositions exist.
