Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136808, here are decompositions:
- 31 + 136777 = 136808
- 97 + 136711 = 136808
- 151 + 136657 = 136808
- 157 + 136651 = 136808
- 271 + 136537 = 136808
- 277 + 136531 = 136808
- 307 + 136501 = 136808
- 337 + 136471 = 136808
Showing the first eight; more decompositions exist.
