Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2260, here are decompositions:

17 + 2243 = 2260
23 + 2237 = 2260
47 + 2213 = 2260
53 + 2207 = 2260
107 + 2153 = 2260
131 + 2129 = 2260
149 + 2111 = 2260
173 + 2087 = 2260

Showing the first eight; more decompositions exist.
