Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26690, here are decompositions:
- 3 + 26687 = 26690
- 7 + 26683 = 26690
- 43 + 26647 = 26690
- 151 + 26539 = 26690
- 193 + 26497 = 26690
- 211 + 26479 = 26690
- 241 + 26449 = 26690
- 283 + 26407 = 26690
Showing the first eight; more decompositions exist.
