Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20056, here are decompositions:
- 5 + 20051 = 20056
- 59 + 19997 = 20056
- 83 + 19973 = 20056
- 107 + 19949 = 20056
- 137 + 19919 = 20056
- 167 + 19889 = 20056
- 263 + 19793 = 20056
- 293 + 19763 = 20056
Showing the first eight; more decompositions exist.
