Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16284, here are decompositions:
- 11 + 16273 = 16284
- 17 + 16267 = 16284
- 31 + 16253 = 16284
- 53 + 16231 = 16284
- 61 + 16223 = 16284
- 67 + 16217 = 16284
- 97 + 16187 = 16284
- 101 + 16183 = 16284
Showing the first eight; more decompositions exist.
