Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12162, here are decompositions:
- 5 + 12157 = 12162
- 13 + 12149 = 12162
- 19 + 12143 = 12162
- 43 + 12119 = 12162
- 53 + 12109 = 12162
- 61 + 12101 = 12162
- 89 + 12073 = 12162
- 113 + 12049 = 12162
Showing the first eight; more decompositions exist.
