Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8446, here are decompositions:
- 3 + 8443 = 8446
- 17 + 8429 = 8446
- 23 + 8423 = 8446
- 59 + 8387 = 8446
- 83 + 8363 = 8446
- 149 + 8297 = 8446
- 173 + 8273 = 8446
- 227 + 8219 = 8446
Showing the first eight; more decompositions exist.
