Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2104, here are decompositions:
- 5 + 2099 = 2104
- 17 + 2087 = 2104
- 23 + 2081 = 2104
- 41 + 2063 = 2104
- 101 + 2003 = 2104
- 107 + 1997 = 2104
- 131 + 1973 = 2104
- 173 + 1931 = 2104
Showing the first eight; more decompositions exist.
