Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18798, here are decompositions:
- 5 + 18793 = 18798
- 11 + 18787 = 18798
- 41 + 18757 = 18798
- 67 + 18731 = 18798
- 79 + 18719 = 18798
- 97 + 18701 = 18798
- 107 + 18691 = 18798
- 127 + 18671 = 18798
Showing the first eight; more decompositions exist.
