Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6406, here are decompositions:
- 17 + 6389 = 6406
- 47 + 6359 = 6406
- 53 + 6353 = 6406
- 83 + 6323 = 6406
- 89 + 6317 = 6406
- 107 + 6299 = 6406
- 137 + 6269 = 6406
- 149 + 6257 = 6406
Showing the first eight; more decompositions exist.
