Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170970, here are decompositions:

13 + 170957 = 170970
17 + 170953 = 170970
43 + 170927 = 170970
71 + 170899 = 170970
83 + 170887 = 170970
89 + 170881 = 170970
97 + 170873 = 170970
113 + 170857 = 170970

Showing the first eight; more decompositions exist.
