Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20038, here are decompositions:
- 17 + 20021 = 20038
- 41 + 19997 = 20038
- 47 + 19991 = 20038
- 59 + 19979 = 20038
- 89 + 19949 = 20038
- 101 + 19937 = 20038
- 149 + 19889 = 20038
- 197 + 19841 = 20038
Showing the first eight; more decompositions exist.
