Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11868, here are decompositions:
- 5 + 11863 = 11868
- 29 + 11839 = 11868
- 37 + 11831 = 11868
- 41 + 11827 = 11868
- 47 + 11821 = 11868
- 61 + 11807 = 11868
- 67 + 11801 = 11868
- 79 + 11789 = 11868
Showing the first eight; more decompositions exist.
