Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170980, here are decompositions:

23 + 170957 = 170980
53 + 170927 = 170980
59 + 170921 = 170980
107 + 170873 = 170980
137 + 170843 = 170980
167 + 170813 = 170980
179 + 170801 = 170980
239 + 170741 = 170980

Showing the first eight; more decompositions exist.
