Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126736, here are decompositions:
- 3 + 126733 = 126736
- 17 + 126719 = 126736
- 23 + 126713 = 126736
- 53 + 126683 = 126736
- 83 + 126653 = 126736
- 263 + 126473 = 126736
- 293 + 126443 = 126736
- 419 + 126317 = 126736
Showing the first eight; more decompositions exist.
