Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2320, here are decompositions:

11 + 2309 = 2320
23 + 2297 = 2320
47 + 2273 = 2320
53 + 2267 = 2320
83 + 2237 = 2320
107 + 2213 = 2320
113 + 2207 = 2320
167 + 2153 = 2320

Showing the first eight; more decompositions exist.
