Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118690, here are decompositions:
- 3 + 118687 = 118690
- 17 + 118673 = 118690
- 29 + 118661 = 118690
- 71 + 118619 = 118690
- 101 + 118589 = 118690
- 107 + 118583 = 118690
- 197 + 118493 = 118690
- 227 + 118463 = 118690
Showing the first eight; more decompositions exist.
