Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16230, here are decompositions:
- 7 + 16223 = 16230
- 13 + 16217 = 16230
- 37 + 16193 = 16230
- 41 + 16189 = 16230
- 43 + 16187 = 16230
- 47 + 16183 = 16230
- 89 + 16141 = 16230
- 103 + 16127 = 16230
Showing the first eight; more decompositions exist.
