Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2270, here are decompositions:

3 + 2267 = 2270
19 + 2251 = 2270
31 + 2239 = 2270
67 + 2203 = 2270
109 + 2161 = 2270
127 + 2143 = 2270
139 + 2131 = 2270
157 + 2113 = 2270

Showing the first eight; more decompositions exist.
