Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136838, here are decompositions:
- 61 + 136777 = 136838
- 127 + 136711 = 136838
- 181 + 136657 = 136838
- 307 + 136531 = 136838
- 337 + 136501 = 136838
- 367 + 136471 = 136838
- 409 + 136429 = 136838
- 421 + 136417 = 136838
Showing the first eight; more decompositions exist.
