Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20316, here are decompositions:
- 19 + 20297 = 20316
- 29 + 20287 = 20316
- 47 + 20269 = 20316
- 67 + 20249 = 20316
- 83 + 20233 = 20316
- 97 + 20219 = 20316
- 139 + 20177 = 20316
- 167 + 20149 = 20316
Showing the first eight; more decompositions exist.
