Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16398, here are decompositions:
- 17 + 16381 = 16398
- 29 + 16369 = 16398
- 37 + 16361 = 16398
- 59 + 16339 = 16398
- 79 + 16319 = 16398
- 97 + 16301 = 16398
- 131 + 16267 = 16398
- 149 + 16249 = 16398
Showing the first eight; more decompositions exist.
