Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72756, here are decompositions:
- 17 + 72739 = 72756
- 23 + 72733 = 72756
- 29 + 72727 = 72756
- 37 + 72719 = 72756
- 67 + 72689 = 72756
- 83 + 72673 = 72756
- 107 + 72649 = 72756
- 109 + 72647 = 72756
Showing the first eight; more decompositions exist.
