Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64420, here are decompositions:
- 17 + 64403 = 64420
- 47 + 64373 = 64420
- 101 + 64319 = 64420
- 137 + 64283 = 64420
- 149 + 64271 = 64420
- 197 + 64223 = 64420
- 233 + 64187 = 64420
- 263 + 64157 = 64420
Showing the first eight; more decompositions exist.
