Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26986, here are decompositions:
- 5 + 26981 = 26986
- 59 + 26927 = 26986
- 83 + 26903 = 26986
- 107 + 26879 = 26986
- 137 + 26849 = 26986
- 173 + 26813 = 26986
- 227 + 26759 = 26986
- 257 + 26729 = 26986
Showing the first eight; more decompositions exist.
