Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12122, here are decompositions:
- 3 + 12119 = 12122
- 13 + 12109 = 12122
- 73 + 12049 = 12122
- 79 + 12043 = 12122
- 151 + 11971 = 12122
- 163 + 11959 = 12122
- 181 + 11941 = 12122
- 199 + 11923 = 12122
Showing the first eight; more decompositions exist.
