Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13408, here are decompositions:
- 11 + 13397 = 13408
- 41 + 13367 = 13408
- 71 + 13337 = 13408
- 149 + 13259 = 13408
- 167 + 13241 = 13408
- 179 + 13229 = 13408
- 191 + 13217 = 13408
- 257 + 13151 = 13408
Showing the first eight; more decompositions exist.
