Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16212, here are decompositions:
- 19 + 16193 = 16212
- 23 + 16189 = 16212
- 29 + 16183 = 16212
- 71 + 16141 = 16212
- 73 + 16139 = 16212
- 101 + 16111 = 16212
- 109 + 16103 = 16212
- 139 + 16073 = 16212
Showing the first eight; more decompositions exist.
