Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660904, here are decompositions:
- 13 + 8660891 = 8660904
- 17 + 8660887 = 8660904
- 41 + 8660863 = 8660904
- 107 + 8660797 = 8660904
- 137 + 8660767 = 8660904
- 151 + 8660753 = 8660904
- 157 + 8660747 = 8660904
- 163 + 8660741 = 8660904
Showing the first eight; more decompositions exist.
