Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66568, here are decompositions:
- 59 + 66509 = 66568
- 101 + 66467 = 66568
- 137 + 66431 = 66568
- 191 + 66377 = 66568
- 347 + 66221 = 66568
- 389 + 66179 = 66568
- 431 + 66137 = 66568
- 461 + 66107 = 66568
Showing the first eight; more decompositions exist.
