Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643108, here are decompositions:
- 17 + 8643091 = 8643108
- 31 + 8643077 = 8643108
- 157 + 8642951 = 8643108
- 181 + 8642927 = 8643108
- 197 + 8642911 = 8643108
- 211 + 8642897 = 8643108
- 251 + 8642857 = 8643108
- 269 + 8642839 = 8643108
Showing the first eight; more decompositions exist.
