Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667920, here are decompositions:
- 7 + 8667913 = 8667920
- 13 + 8667907 = 8667920
- 73 + 8667847 = 8667920
- 127 + 8667793 = 8667920
- 193 + 8667727 = 8667920
- 199 + 8667721 = 8667920
- 223 + 8667697 = 8667920
- 307 + 8667613 = 8667920
Showing the first eight; more decompositions exist.
