Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718178, here are decompositions:

89 + 8718089 = 8718178
167 + 8718011 = 8718178
179 + 8717999 = 8718178
191 + 8717987 = 8718178
197 + 8717981 = 8718178
239 + 8717939 = 8718178
251 + 8717927 = 8718178
269 + 8717909 = 8718178

Showing the first eight; more decompositions exist.
