Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64320, here are decompositions:
- 17 + 64303 = 64320
- 19 + 64301 = 64320
- 37 + 64283 = 64320
- 41 + 64279 = 64320
- 83 + 64237 = 64320
- 89 + 64231 = 64320
- 97 + 64223 = 64320
- 103 + 64217 = 64320
Showing the first eight; more decompositions exist.
