Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172006, here are decompositions:

5 + 172001 = 172006
59 + 171947 = 172006
83 + 171923 = 172006
89 + 171917 = 172006
137 + 171869 = 172006
179 + 171827 = 172006
293 + 171713 = 172006
347 + 171659 = 172006

Showing the first eight; more decompositions exist.
