Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80960, here are decompositions:
- 7 + 80953 = 80960
- 31 + 80929 = 80960
- 37 + 80923 = 80960
- 43 + 80917 = 80960
- 97 + 80863 = 80960
- 127 + 80833 = 80960
- 151 + 80809 = 80960
- 157 + 80803 = 80960
Showing the first eight; more decompositions exist.
