Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737440, here are decompositions:
- 7 + 8737433 = 8737440
- 13 + 8737427 = 8737440
- 17 + 8737423 = 8737440
- 67 + 8737373 = 8737440
- 83 + 8737357 = 8737440
- 97 + 8737343 = 8737440
- 139 + 8737301 = 8737440
- 163 + 8737277 = 8737440
Showing the first eight; more decompositions exist.
