Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178960, here are decompositions:

29 + 178931 = 178960
53 + 178907 = 178960
71 + 178889 = 178960
83 + 178877 = 178960
101 + 178859 = 178960
107 + 178853 = 178960
167 + 178793 = 178960
179 + 178781 = 178960

Showing the first eight; more decompositions exist.
