Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668948, here are decompositions:
- 47 + 8668901 = 8668948
- 59 + 8668889 = 8668948
- 131 + 8668817 = 8668948
- 149 + 8668799 = 8668948
- 227 + 8668721 = 8668948
- 251 + 8668697 = 8668948
- 311 + 8668637 = 8668948
- 401 + 8668547 = 8668948
Showing the first eight; more decompositions exist.
