Goldbach decomposition

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.
