Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20416, here are decompositions:
- 5 + 20411 = 20416
- 17 + 20399 = 20416
- 23 + 20393 = 20416
- 47 + 20369 = 20416
- 59 + 20357 = 20416
- 83 + 20333 = 20416
- 89 + 20327 = 20416
- 167 + 20249 = 20416
Showing the first eight; more decompositions exist.
