Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77724, here are decompositions:
- 5 + 77719 = 77724
- 11 + 77713 = 77724
- 13 + 77711 = 77724
- 37 + 77687 = 77724
- 43 + 77681 = 77724
- 83 + 77641 = 77724
- 103 + 77621 = 77724
- 107 + 77617 = 77724
Showing the first eight; more decompositions exist.
