Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20882, here are decompositions:
- 3 + 20879 = 20882
- 73 + 20809 = 20882
- 109 + 20773 = 20882
- 139 + 20743 = 20882
- 151 + 20731 = 20882
- 163 + 20719 = 20882
- 241 + 20641 = 20882
- 271 + 20611 = 20882
Showing the first eight; more decompositions exist.
