Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20212, here are decompositions:
- 11 + 20201 = 20212
- 29 + 20183 = 20212
- 83 + 20129 = 20212
- 89 + 20123 = 20212
- 149 + 20063 = 20212
- 191 + 20021 = 20212
- 233 + 19979 = 20212
- 239 + 19973 = 20212
Showing the first eight; more decompositions exist.
