Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28344, here are decompositions:
- 37 + 28307 = 28344
- 47 + 28297 = 28344
- 61 + 28283 = 28344
- 67 + 28277 = 28344
- 163 + 28181 = 28344
- 181 + 28163 = 28344
- 193 + 28151 = 28344
- 233 + 28111 = 28344
Showing the first eight; more decompositions exist.
