Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17998, here are decompositions:
- 11 + 17987 = 17998
- 17 + 17981 = 17998
- 41 + 17957 = 17998
- 59 + 17939 = 17998
- 89 + 17909 = 17998
- 107 + 17891 = 17998
- 191 + 17807 = 17998
- 251 + 17747 = 17998
Showing the first eight; more decompositions exist.
