Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77806, here are decompositions:
- 5 + 77801 = 77806
- 23 + 77783 = 77806
- 59 + 77747 = 77806
- 83 + 77723 = 77806
- 107 + 77699 = 77806
- 233 + 77573 = 77806
- 257 + 77549 = 77806
- 263 + 77543 = 77806
Showing the first eight; more decompositions exist.
