Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185824, here are decompositions:

3 + 185821 = 185824
5 + 185819 = 185824
11 + 185813 = 185824
71 + 185753 = 185824
101 + 185723 = 185824
113 + 185711 = 185824
131 + 185693 = 185824
173 + 185651 = 185824

Showing the first eight; more decompositions exist.
