Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 736, here are decompositions:
- 3 + 733 = 736
- 17 + 719 = 736
- 53 + 683 = 736
- 59 + 677 = 736
- 83 + 653 = 736
- 89 + 647 = 736
- 137 + 599 = 736
- 149 + 587 = 736
Showing the first eight; more decompositions exist.
