Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173218, here are decompositions:

11 + 173207 = 173218
29 + 173189 = 173218
41 + 173177 = 173218
131 + 173087 = 173218
137 + 173081 = 173218
179 + 173039 = 173218
197 + 173021 = 173218
347 + 172871 = 173218

Showing the first eight; more decompositions exist.
