Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11800, here are decompositions:
- 11 + 11789 = 11800
- 17 + 11783 = 11800
- 23 + 11777 = 11800
- 83 + 11717 = 11800
- 101 + 11699 = 11800
- 167 + 11633 = 11800
- 179 + 11621 = 11800
- 251 + 11549 = 11800
Showing the first eight; more decompositions exist.
