Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12126, here are decompositions:
- 7 + 12119 = 12126
- 13 + 12113 = 12126
- 17 + 12109 = 12126
- 19 + 12107 = 12126
- 29 + 12097 = 12126
- 53 + 12073 = 12126
- 83 + 12043 = 12126
- 89 + 12037 = 12126
Showing the first eight; more decompositions exist.
