Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12354, here are decompositions:
- 7 + 12347 = 12354
- 11 + 12343 = 12354
- 31 + 12323 = 12354
- 53 + 12301 = 12354
- 73 + 12281 = 12354
- 101 + 12253 = 12354
- 103 + 12251 = 12354
- 113 + 12241 = 12354
Showing the first eight; more decompositions exist.
