Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170978, here are decompositions:

7 + 170971 = 170978
79 + 170899 = 170978
97 + 170881 = 170978
127 + 170851 = 170978
151 + 170827 = 170978
211 + 170767 = 170978
229 + 170749 = 170978
271 + 170707 = 170978

Showing the first eight; more decompositions exist.
