Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669668, here are decompositions:
- 11 + 8669657 = 8669668
- 17 + 8669651 = 8669668
- 41 + 8669627 = 8669668
- 47 + 8669621 = 8669668
- 167 + 8669501 = 8669668
- 179 + 8669489 = 8669668
- 191 + 8669477 = 8669668
- 251 + 8669417 = 8669668
Showing the first eight; more decompositions exist.
