Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12242, here are decompositions:
- 3 + 12239 = 12242
- 31 + 12211 = 12242
- 79 + 12163 = 12242
- 193 + 12049 = 12242
- 199 + 12043 = 12242
- 271 + 11971 = 12242
- 283 + 11959 = 12242
- 379 + 11863 = 12242
Showing the first eight; more decompositions exist.
