Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667644, here are decompositions:
- 3 + 8667641 = 8667644
- 31 + 8667613 = 8667644
- 43 + 8667601 = 8667644
- 241 + 8667403 = 8667644
- 331 + 8667313 = 8667644
- 373 + 8667271 = 8667644
- 523 + 8667121 = 8667644
- 541 + 8667103 = 8667644
Showing the first eight; more decompositions exist.
