Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17904, here are decompositions:
- 13 + 17891 = 17904
- 23 + 17881 = 17904
- 41 + 17863 = 17904
- 53 + 17851 = 17904
- 67 + 17837 = 17904
- 97 + 17807 = 17904
- 113 + 17791 = 17904
- 157 + 17747 = 17904
Showing the first eight; more decompositions exist.
