Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18344, here are decompositions:
- 3 + 18341 = 18344
- 31 + 18313 = 18344
- 37 + 18307 = 18344
- 43 + 18301 = 18344
- 127 + 18217 = 18344
- 163 + 18181 = 18344
- 211 + 18133 = 18344
- 223 + 18121 = 18344
Showing the first eight; more decompositions exist.
