Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687936, here are decompositions:
- 7 + 8687929 = 8687936
- 13 + 8687923 = 8687936
- 109 + 8687827 = 8687936
- 139 + 8687797 = 8687936
- 223 + 8687713 = 8687936
- 277 + 8687659 = 8687936
- 337 + 8687599 = 8687936
- 349 + 8687587 = 8687936
Showing the first eight; more decompositions exist.
