Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79728, here are decompositions:
- 29 + 79699 = 79728
- 31 + 79697 = 79728
- 37 + 79691 = 79728
- 41 + 79687 = 79728
- 59 + 79669 = 79728
- 71 + 79657 = 79728
- 97 + 79631 = 79728
- 101 + 79627 = 79728
Showing the first eight; more decompositions exist.
