Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 798, here are decompositions:
- 11 + 787 = 798
- 29 + 769 = 798
- 37 + 761 = 798
- 41 + 757 = 798
- 47 + 751 = 798
- 59 + 739 = 798
- 71 + 727 = 798
- 79 + 719 = 798
Showing the first eight; more decompositions exist.
