Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28166, here are decompositions:
- 3 + 28163 = 28166
- 43 + 28123 = 28166
- 67 + 28099 = 28166
- 79 + 28087 = 28166
- 97 + 28069 = 28166
- 109 + 28057 = 28166
- 139 + 28027 = 28166
- 199 + 27967 = 28166
Showing the first eight; more decompositions exist.
