Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6436, here are decompositions:
- 47 + 6389 = 6436
- 83 + 6353 = 6436
- 107 + 6329 = 6436
- 113 + 6323 = 6436
- 137 + 6299 = 6436
- 149 + 6287 = 6436
- 167 + 6269 = 6436
- 173 + 6263 = 6436
Showing the first eight; more decompositions exist.
