Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11862, here are decompositions:

23 + 11839 = 11862
29 + 11833 = 11862
31 + 11831 = 11862
41 + 11821 = 11862
61 + 11801 = 11862
73 + 11789 = 11862
79 + 11783 = 11862
83 + 11779 = 11862

Showing the first eight; more decompositions exist.
