Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125736, here are decompositions:
- 5 + 125731 = 125736
- 19 + 125717 = 125736
- 29 + 125707 = 125736
- 43 + 125693 = 125736
- 53 + 125683 = 125736
- 67 + 125669 = 125736
- 97 + 125639 = 125736
- 109 + 125627 = 125736
Showing the first eight; more decompositions exist.
