Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77730, here are decompositions:
- 7 + 77723 = 77730
- 11 + 77719 = 77730
- 17 + 77713 = 77730
- 19 + 77711 = 77730
- 31 + 77699 = 77730
- 41 + 77689 = 77730
- 43 + 77687 = 77730
- 71 + 77659 = 77730
Showing the first eight; more decompositions exist.
