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.
