Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11886, here are decompositions:
- 19 + 11867 = 11886
- 23 + 11863 = 11886
- 47 + 11839 = 11886
- 53 + 11833 = 11886
- 59 + 11827 = 11886
- 73 + 11813 = 11886
- 79 + 11807 = 11886
- 97 + 11789 = 11886
Showing the first eight; more decompositions exist.
