Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17958, here are decompositions:
- 19 + 17939 = 17958
- 29 + 17929 = 17958
- 37 + 17921 = 17958
- 47 + 17911 = 17958
- 67 + 17891 = 17958
- 107 + 17851 = 17958
- 131 + 17827 = 17958
- 151 + 17807 = 17958
Showing the first eight; more decompositions exist.
