Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12180, here are decompositions:
- 17 + 12163 = 12180
- 19 + 12161 = 12180
- 23 + 12157 = 12180
- 31 + 12149 = 12180
- 37 + 12143 = 12180
- 61 + 12119 = 12180
- 67 + 12113 = 12180
- 71 + 12109 = 12180
Showing the first eight; more decompositions exist.
