Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16216, here are decompositions:
- 23 + 16193 = 16216
- 29 + 16187 = 16216
- 89 + 16127 = 16216
- 113 + 16103 = 16216
- 149 + 16067 = 16216
- 257 + 15959 = 16216
- 293 + 15923 = 16216
- 419 + 15797 = 16216
Showing the first eight; more decompositions exist.
