Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12342, here are decompositions:
- 13 + 12329 = 12342
- 19 + 12323 = 12342
- 41 + 12301 = 12342
- 53 + 12289 = 12342
- 61 + 12281 = 12342
- 73 + 12269 = 12342
- 79 + 12263 = 12342
- 89 + 12253 = 12342
Showing the first eight; more decompositions exist.
