Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79740, here are decompositions:
- 41 + 79699 = 79740
- 43 + 79697 = 79740
- 47 + 79693 = 79740
- 53 + 79687 = 79740
- 71 + 79669 = 79740
- 83 + 79657 = 79740
- 107 + 79633 = 79740
- 109 + 79631 = 79740
Showing the first eight; more decompositions exist.
