Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111166, here are decompositions:
- 17 + 111149 = 111166
- 23 + 111143 = 111166
- 47 + 111119 = 111166
- 113 + 111053 = 111166
- 137 + 111029 = 111166
- 197 + 110969 = 111166
- 227 + 110939 = 111166
- 233 + 110933 = 111166
Showing the first eight; more decompositions exist.
