Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11838, here are decompositions:
- 5 + 11833 = 11838
- 7 + 11831 = 11838
- 11 + 11827 = 11838
- 17 + 11821 = 11838
- 31 + 11807 = 11838
- 37 + 11801 = 11838
- 59 + 11779 = 11838
- 61 + 11777 = 11838
Showing the first eight; more decompositions exist.
