Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42736, here are decompositions:
- 17 + 42719 = 42736
- 47 + 42689 = 42736
- 53 + 42683 = 42736
- 59 + 42677 = 42736
- 167 + 42569 = 42736
- 179 + 42557 = 42736
- 227 + 42509 = 42736
- 263 + 42473 = 42736
Showing the first eight; more decompositions exist.
