Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668998, here are decompositions:
- 5 + 8668993 = 8668998
- 31 + 8668967 = 8668998
- 47 + 8668951 = 8668998
- 97 + 8668901 = 8668998
- 101 + 8668897 = 8668998
- 109 + 8668889 = 8668998
- 167 + 8668831 = 8668998
- 181 + 8668817 = 8668998
Showing the first eight; more decompositions exist.
