Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185842, here are decompositions:

11 + 185831 = 185842
23 + 185819 = 185842
29 + 185813 = 185842
53 + 185789 = 185842
89 + 185753 = 185842
131 + 185711 = 185842
149 + 185693 = 185842
191 + 185651 = 185842

Showing the first eight; more decompositions exist.
