Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12192, here are decompositions:
- 29 + 12163 = 12192
- 31 + 12161 = 12192
- 43 + 12149 = 12192
- 73 + 12119 = 12192
- 79 + 12113 = 12192
- 83 + 12109 = 12192
- 149 + 12043 = 12192
- 151 + 12041 = 12192
Showing the first eight; more decompositions exist.
