Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2290, here are decompositions:

3 + 2287 = 2290
17 + 2273 = 2290
23 + 2267 = 2290
47 + 2243 = 2290
53 + 2237 = 2290
83 + 2207 = 2290
137 + 2153 = 2290
149 + 2141 = 2290

Showing the first eight; more decompositions exist.
