Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667688, here are decompositions:
- 11 + 8667677 = 8667688
- 47 + 8667641 = 8667688
- 149 + 8667539 = 8667688
- 167 + 8667521 = 8667688
- 191 + 8667497 = 8667688
- 257 + 8667431 = 8667688
- 269 + 8667419 = 8667688
- 311 + 8667377 = 8667688
Showing the first eight; more decompositions exist.
