Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11986, here are decompositions:
- 5 + 11981 = 11986
- 17 + 11969 = 11986
- 47 + 11939 = 11986
- 53 + 11933 = 11986
- 59 + 11927 = 11986
- 83 + 11903 = 11986
- 89 + 11897 = 11986
- 173 + 11813 = 11986
Showing the first eight; more decompositions exist.
