Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2208, here are decompositions:
- 5 + 2203 = 2208
- 29 + 2179 = 2208
- 47 + 2161 = 2208
- 67 + 2141 = 2208
- 71 + 2137 = 2208
- 79 + 2129 = 2208
- 97 + 2111 = 2208
- 109 + 2099 = 2208
Showing the first eight; more decompositions exist.
