Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80256, here are decompositions:
- 5 + 80251 = 80256
- 17 + 80239 = 80256
- 23 + 80233 = 80256
- 47 + 80209 = 80256
- 79 + 80177 = 80256
- 83 + 80173 = 80256
- 89 + 80167 = 80256
- 103 + 80153 = 80256
Showing the first eight; more decompositions exist.
