Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16664, here are decompositions:
- 3 + 16661 = 16664
- 7 + 16657 = 16664
- 13 + 16651 = 16664
- 31 + 16633 = 16664
- 61 + 16603 = 16664
- 97 + 16567 = 16664
- 103 + 16561 = 16664
- 211 + 16453 = 16664
Showing the first eight; more decompositions exist.
