Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64540, here are decompositions:
- 41 + 64499 = 64540
- 89 + 64451 = 64540
- 101 + 64439 = 64540
- 107 + 64433 = 64540
- 137 + 64403 = 64540
- 167 + 64373 = 64540
- 239 + 64301 = 64540
- 257 + 64283 = 64540
Showing the first eight; more decompositions exist.
