Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660960, here are decompositions:
- 13 + 8660947 = 8660960
- 31 + 8660929 = 8660960
- 73 + 8660887 = 8660960
- 97 + 8660863 = 8660960
- 163 + 8660797 = 8660960
- 193 + 8660767 = 8660960
- 271 + 8660689 = 8660960
- 277 + 8660683 = 8660960
Showing the first eight; more decompositions exist.
