Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76860, here are decompositions:
- 13 + 76847 = 76860
- 23 + 76837 = 76860
- 29 + 76831 = 76860
- 31 + 76829 = 76860
- 41 + 76819 = 76860
- 59 + 76801 = 76860
- 79 + 76781 = 76860
- 83 + 76777 = 76860
Showing the first eight; more decompositions exist.
