Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12110, here are decompositions:
- 3 + 12107 = 12110
- 13 + 12097 = 12110
- 37 + 12073 = 12110
- 61 + 12049 = 12110
- 67 + 12043 = 12110
- 73 + 12037 = 12110
- 103 + 12007 = 12110
- 139 + 11971 = 12110
Showing the first eight; more decompositions exist.
