Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2380, here are decompositions:
- 3 + 2377 = 2380
- 23 + 2357 = 2380
- 29 + 2351 = 2380
- 41 + 2339 = 2380
- 47 + 2333 = 2380
- 71 + 2309 = 2380
- 83 + 2297 = 2380
- 107 + 2273 = 2380
Showing the first eight; more decompositions exist.
