Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12312, here are decompositions:
- 11 + 12301 = 12312
- 23 + 12289 = 12312
- 31 + 12281 = 12312
- 43 + 12269 = 12312
- 59 + 12253 = 12312
- 61 + 12251 = 12312
- 71 + 12241 = 12312
- 73 + 12239 = 12312
Showing the first eight; more decompositions exist.
