Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40464, here are decompositions:
- 5 + 40459 = 40464
- 31 + 40433 = 40464
- 37 + 40427 = 40464
- 41 + 40423 = 40464
- 103 + 40361 = 40464
- 107 + 40357 = 40464
- 113 + 40351 = 40464
- 181 + 40283 = 40464
Showing the first eight; more decompositions exist.
