Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185836, here are decompositions:

3 + 185833 = 185836
5 + 185831 = 185836
17 + 185819 = 185836
23 + 185813 = 185836
47 + 185789 = 185836
83 + 185753 = 185836
89 + 185747 = 185836
113 + 185723 = 185836

Showing the first eight; more decompositions exist.
