Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16180, here are decompositions:

41 + 16139 = 16180
53 + 16127 = 16180
83 + 16097 = 16180
89 + 16091 = 16180
107 + 16073 = 16180
113 + 16067 = 16180
173 + 16007 = 16180
179 + 16001 = 16180

Showing the first eight; more decompositions exist.
