Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16380, here are decompositions:
- 11 + 16369 = 16380
- 17 + 16363 = 16380
- 19 + 16361 = 16380
- 31 + 16349 = 16380
- 41 + 16339 = 16380
- 47 + 16333 = 16380
- 61 + 16319 = 16380
- 79 + 16301 = 16380
Showing the first eight; more decompositions exist.
