Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26890, here are decompositions:
- 11 + 26879 = 26890
- 29 + 26861 = 26890
- 41 + 26849 = 26890
- 89 + 26801 = 26890
- 107 + 26783 = 26890
- 113 + 26777 = 26890
- 131 + 26759 = 26890
- 167 + 26723 = 26890
Showing the first eight; more decompositions exist.
