Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12318, here are decompositions:
- 17 + 12301 = 12318
- 29 + 12289 = 12318
- 37 + 12281 = 12318
- 41 + 12277 = 12318
- 67 + 12251 = 12318
- 79 + 12239 = 12318
- 107 + 12211 = 12318
- 157 + 12161 = 12318
Showing the first eight; more decompositions exist.
