Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11992, here are decompositions:
- 5 + 11987 = 11992
- 11 + 11981 = 11992
- 23 + 11969 = 11992
- 53 + 11939 = 11992
- 59 + 11933 = 11992
- 83 + 11909 = 11992
- 89 + 11903 = 11992
- 179 + 11813 = 11992
Showing the first eight; more decompositions exist.
