Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10406, here are decompositions:
- 7 + 10399 = 10406
- 37 + 10369 = 10406
- 73 + 10333 = 10406
- 103 + 10303 = 10406
- 139 + 10267 = 10406
- 163 + 10243 = 10406
- 229 + 10177 = 10406
- 307 + 10099 = 10406
Showing the first eight; more decompositions exist.
