Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118816, here are decompositions:
- 17 + 118799 = 118816
- 29 + 118787 = 118816
- 59 + 118757 = 118816
- 107 + 118709 = 118816
- 197 + 118619 = 118816
- 227 + 118589 = 118816
- 233 + 118583 = 118816
- 353 + 118463 = 118816
Showing the first eight; more decompositions exist.
