Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667668, here are decompositions:
- 7 + 8667661 = 8667668
- 67 + 8667601 = 8667668
- 109 + 8667559 = 8667668
- 157 + 8667511 = 8667668
- 211 + 8667457 = 8667668
- 241 + 8667427 = 8667668
- 349 + 8667319 = 8667668
- 367 + 8667301 = 8667668
Showing the first eight; more decompositions exist.
