Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20192, here are decompositions:
- 19 + 20173 = 20192
- 31 + 20161 = 20192
- 43 + 20149 = 20192
- 79 + 20113 = 20192
- 103 + 20089 = 20192
- 163 + 20029 = 20192
- 181 + 20011 = 20192
- 199 + 19993 = 20192
Showing the first eight; more decompositions exist.
