Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171078, here are decompositions:

29 + 171049 = 171078
31 + 171047 = 171078
71 + 171007 = 171078
107 + 170971 = 171078
151 + 170927 = 171078
157 + 170921 = 171078
179 + 170899 = 171078
191 + 170887 = 171078

Showing the first eight; more decompositions exist.
