Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64642, here are decompositions:
- 29 + 64613 = 64642
- 41 + 64601 = 64642
- 89 + 64553 = 64642
- 191 + 64451 = 64642
- 239 + 64403 = 64642
- 269 + 64373 = 64642
- 359 + 64283 = 64642
- 419 + 64223 = 64642
Showing the first eight; more decompositions exist.
