Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20266, here are decompositions:
- 5 + 20261 = 20266
- 17 + 20249 = 20266
- 47 + 20219 = 20266
- 83 + 20183 = 20266
- 89 + 20177 = 20266
- 137 + 20129 = 20266
- 149 + 20117 = 20266
- 269 + 19997 = 20266
Showing the first eight; more decompositions exist.
