Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10408, here are decompositions:
- 17 + 10391 = 10408
- 71 + 10337 = 10408
- 107 + 10301 = 10408
- 137 + 10271 = 10408
- 149 + 10259 = 10408
- 197 + 10211 = 10408
- 227 + 10181 = 10408
- 239 + 10169 = 10408
Showing the first eight; more decompositions exist.
