Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16390, here are decompositions:
- 29 + 16361 = 16390
- 41 + 16349 = 16390
- 71 + 16319 = 16390
- 89 + 16301 = 16390
- 137 + 16253 = 16390
- 167 + 16223 = 16390
- 173 + 16217 = 16390
- 197 + 16193 = 16390
Showing the first eight; more decompositions exist.
