Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708160, here are decompositions:
- 7 + 8708153 = 8708160
- 17 + 8708143 = 8708160
- 31 + 8708129 = 8708160
- 59 + 8708101 = 8708160
- 67 + 8708093 = 8708160
- 73 + 8708087 = 8708160
- 79 + 8708081 = 8708160
- 89 + 8708071 = 8708160
Showing the first eight; more decompositions exist.
