Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18716, here are decompositions:
- 3 + 18713 = 18716
- 37 + 18679 = 18716
- 79 + 18637 = 18716
- 163 + 18553 = 18716
- 193 + 18523 = 18716
- 199 + 18517 = 18716
- 223 + 18493 = 18716
- 277 + 18439 = 18716
Showing the first eight; more decompositions exist.
