Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16386, here are decompositions:
- 5 + 16381 = 16386
- 17 + 16369 = 16386
- 23 + 16363 = 16386
- 37 + 16349 = 16386
- 47 + 16339 = 16386
- 53 + 16333 = 16386
- 67 + 16319 = 16386
- 113 + 16273 = 16386
Showing the first eight; more decompositions exist.
