Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16278, here are decompositions:
- 5 + 16273 = 16278
- 11 + 16267 = 16278
- 29 + 16249 = 16278
- 47 + 16231 = 16278
- 61 + 16217 = 16278
- 89 + 16189 = 16278
- 137 + 16141 = 16278
- 139 + 16139 = 16278
Showing the first eight; more decompositions exist.
