Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12206, here are decompositions:
- 3 + 12203 = 12206
- 43 + 12163 = 12206
- 97 + 12109 = 12206
- 109 + 12097 = 12206
- 157 + 12049 = 12206
- 163 + 12043 = 12206
- 199 + 12007 = 12206
- 283 + 11923 = 12206
Showing the first eight; more decompositions exist.
