Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2108, here are decompositions:
- 19 + 2089 = 2108
- 79 + 2029 = 2108
- 97 + 2011 = 2108
- 109 + 1999 = 2108
- 157 + 1951 = 2108
- 229 + 1879 = 2108
- 241 + 1867 = 2108
- 277 + 1831 = 2108
Showing the first eight; more decompositions exist.
