Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16206, here are decompositions:
- 13 + 16193 = 16206
- 17 + 16189 = 16206
- 19 + 16187 = 16206
- 23 + 16183 = 16206
- 67 + 16139 = 16206
- 79 + 16127 = 16206
- 103 + 16103 = 16206
- 109 + 16097 = 16206
Showing the first eight; more decompositions exist.
