Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20206, here are decompositions:
- 5 + 20201 = 20206
- 23 + 20183 = 20206
- 29 + 20177 = 20206
- 59 + 20147 = 20206
- 83 + 20123 = 20206
- 89 + 20117 = 20206
- 227 + 19979 = 20206
- 233 + 19973 = 20206
Showing the first eight; more decompositions exist.
