Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634178, here are decompositions:

5 + 8634173 = 8634178
17 + 8634161 = 8634178
41 + 8634137 = 8634178
71 + 8634107 = 8634178
101 + 8634077 = 8634178
197 + 8633981 = 8634178
227 + 8633951 = 8634178
239 + 8633939 = 8634178

Showing the first eight; more decompositions exist.
