Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708080, here are decompositions:
- 11 + 8708069 = 8708080
- 41 + 8708039 = 8708080
- 83 + 8707997 = 8708080
- 197 + 8707883 = 8708080
- 239 + 8707841 = 8708080
- 263 + 8707817 = 8708080
- 317 + 8707763 = 8708080
- 383 + 8707697 = 8708080
Showing the first eight; more decompositions exist.
