Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 726, here are decompositions:
- 7 + 719 = 726
- 17 + 709 = 726
- 43 + 683 = 726
- 53 + 673 = 726
- 67 + 659 = 726
- 73 + 653 = 726
- 79 + 647 = 726
- 83 + 643 = 726
Showing the first eight; more decompositions exist.
