Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12156, here are decompositions:
- 7 + 12149 = 12156
- 13 + 12143 = 12156
- 37 + 12119 = 12156
- 43 + 12113 = 12156
- 47 + 12109 = 12156
- 59 + 12097 = 12156
- 83 + 12073 = 12156
- 107 + 12049 = 12156
Showing the first eight; more decompositions exist.
