Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171018, here are decompositions:

11 + 171007 = 171018
47 + 170971 = 171018
61 + 170957 = 171018
97 + 170921 = 171018
131 + 170887 = 171018
137 + 170881 = 171018
167 + 170851 = 171018
181 + 170837 = 171018

Showing the first eight; more decompositions exist.
