Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16248, here are decompositions:
- 17 + 16231 = 16248
- 19 + 16229 = 16248
- 31 + 16217 = 16248
- 59 + 16189 = 16248
- 61 + 16187 = 16248
- 107 + 16141 = 16248
- 109 + 16139 = 16248
- 137 + 16111 = 16248
Showing the first eight; more decompositions exist.
