Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16724, here are decompositions:
- 31 + 16693 = 16724
- 67 + 16657 = 16724
- 73 + 16651 = 16724
- 151 + 16573 = 16724
- 157 + 16567 = 16724
- 163 + 16561 = 16724
- 271 + 16453 = 16724
- 277 + 16447 = 16724
Showing the first eight; more decompositions exist.
