Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80668, here are decompositions:
- 11 + 80657 = 80668
- 17 + 80651 = 80668
- 41 + 80627 = 80668
- 47 + 80621 = 80668
- 101 + 80567 = 80668
- 131 + 80537 = 80668
- 179 + 80489 = 80668
- 197 + 80471 = 80668
Showing the first eight; more decompositions exist.
