Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2338, here are decompositions:
- 5 + 2333 = 2338
- 29 + 2309 = 2338
- 41 + 2297 = 2338
- 71 + 2267 = 2338
- 101 + 2237 = 2338
- 131 + 2207 = 2338
- 197 + 2141 = 2338
- 227 + 2111 = 2338
Showing the first eight; more decompositions exist.
