Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16272, here are decompositions:
- 5 + 16267 = 16272
- 19 + 16253 = 16272
- 23 + 16249 = 16272
- 41 + 16231 = 16272
- 43 + 16229 = 16272
- 79 + 16193 = 16272
- 83 + 16189 = 16272
- 89 + 16183 = 16272
Showing the first eight; more decompositions exist.
