Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2206, here are decompositions:
- 3 + 2203 = 2206
- 53 + 2153 = 2206
- 107 + 2099 = 2206
- 137 + 2069 = 2206
- 167 + 2039 = 2206
- 179 + 2027 = 2206
- 227 + 1979 = 2206
- 233 + 1973 = 2206
Showing the first eight; more decompositions exist.
