Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12132, here are decompositions:
- 13 + 12119 = 12132
- 19 + 12113 = 12132
- 23 + 12109 = 12132
- 31 + 12101 = 12132
- 59 + 12073 = 12132
- 61 + 12071 = 12132
- 83 + 12049 = 12132
- 89 + 12043 = 12132
Showing the first eight; more decompositions exist.
