Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178916, here are decompositions:

7 + 178909 = 178916
13 + 178903 = 178916
19 + 178897 = 178916
43 + 178873 = 178916
97 + 178819 = 178916
103 + 178813 = 178916
109 + 178807 = 178916
163 + 178753 = 178916

Showing the first eight; more decompositions exist.
