Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179986, here are decompositions:

5 + 179981 = 179986
17 + 179969 = 179986
29 + 179957 = 179986
47 + 179939 = 179986
83 + 179903 = 179986
89 + 179897 = 179986
137 + 179849 = 179986
167 + 179819 = 179986

Showing the first eight; more decompositions exist.
