Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28384, here are decompositions:
- 101 + 28283 = 28384
- 107 + 28277 = 28384
- 173 + 28211 = 28384
- 233 + 28151 = 28384
- 353 + 28031 = 28384
- 383 + 28001 = 28384
- 401 + 27983 = 28384
- 431 + 27953 = 28384
Showing the first eight; more decompositions exist.
