Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77760, here are decompositions:
- 13 + 77747 = 77760
- 17 + 77743 = 77760
- 29 + 77731 = 77760
- 37 + 77723 = 77760
- 41 + 77719 = 77760
- 47 + 77713 = 77760
- 61 + 77699 = 77760
- 71 + 77689 = 77760
Showing the first eight; more decompositions exist.
