Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17858, here are decompositions:
- 7 + 17851 = 17858
- 19 + 17839 = 17858
- 31 + 17827 = 17858
- 67 + 17791 = 17858
- 97 + 17761 = 17858
- 109 + 17749 = 17858
- 151 + 17707 = 17858
- 199 + 17659 = 17858
Showing the first eight; more decompositions exist.
