Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16402, here are decompositions:
- 41 + 16361 = 16402
- 53 + 16349 = 16402
- 83 + 16319 = 16402
- 101 + 16301 = 16402
- 149 + 16253 = 16402
- 173 + 16229 = 16402
- 179 + 16223 = 16402
- 263 + 16139 = 16402
Showing the first eight; more decompositions exist.
