Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178824, here are decompositions:

5 + 178819 = 178824
7 + 178817 = 178824
11 + 178813 = 178824
17 + 178807 = 178824
31 + 178793 = 178824
43 + 178781 = 178824
67 + 178757 = 178824
71 + 178753 = 178824

Showing the first eight; more decompositions exist.
