Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20494, here are decompositions:
- 11 + 20483 = 20494
- 17 + 20477 = 20494
- 53 + 20441 = 20494
- 83 + 20411 = 20494
- 101 + 20393 = 20494
- 137 + 20357 = 20494
- 167 + 20327 = 20494
- 197 + 20297 = 20494
Showing the first eight; more decompositions exist.
