Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543736, here are decompositions:
- 13 + 31543723 = 31543736
- 67 + 31543669 = 31543736
- 157 + 31543579 = 31543736
- 193 + 31543543 = 31543736
- 283 + 31543453 = 31543736
- 307 + 31543429 = 31543736
- 463 + 31543273 = 31543736
- 727 + 31543009 = 31543736
Showing the first eight; more decompositions exist.
