Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2384, here are decompositions:
- 3 + 2381 = 2384
- 7 + 2377 = 2384
- 13 + 2371 = 2384
- 37 + 2347 = 2384
- 43 + 2341 = 2384
- 73 + 2311 = 2384
- 97 + 2287 = 2384
- 103 + 2281 = 2384
Showing the first eight; more decompositions exist.
