Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71736, here are decompositions:
- 17 + 71719 = 71736
- 23 + 71713 = 71736
- 29 + 71707 = 71736
- 37 + 71699 = 71736
- 43 + 71693 = 71736
- 73 + 71663 = 71736
- 89 + 71647 = 71736
- 103 + 71633 = 71736
Showing the first eight; more decompositions exist.
