Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166570, here are decompositions:

3 + 166567 = 166570
29 + 166541 = 166570
83 + 166487 = 166570
113 + 166457 = 166570
167 + 166403 = 166570
251 + 166319 = 166570
269 + 166301 = 166570
281 + 166289 = 166570

Showing the first eight; more decompositions exist.
