Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676668, here are decompositions:
- 37 + 8676631 = 8676668
- 67 + 8676601 = 8676668
- 127 + 8676541 = 8676668
- 151 + 8676517 = 8676668
- 181 + 8676487 = 8676668
- 271 + 8676397 = 8676668
- 307 + 8676361 = 8676668
- 331 + 8676337 = 8676668
Showing the first eight; more decompositions exist.
