Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716178, here are decompositions:

19 + 8716159 = 8716178
109 + 8716069 = 8716178
139 + 8716039 = 8716178
151 + 8716027 = 8716178
157 + 8716021 = 8716178
241 + 8715937 = 8716178
271 + 8715907 = 8716178
277 + 8715901 = 8716178

Showing the first eight; more decompositions exist.
