Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185844, here are decompositions:

11 + 185833 = 185844
13 + 185831 = 185844
23 + 185821 = 185844
31 + 185813 = 185844
47 + 185797 = 185844
97 + 185747 = 185844
107 + 185737 = 185844
137 + 185707 = 185844

Showing the first eight; more decompositions exist.
