Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684178, here are decompositions:

5 + 8684173 = 8684178
7 + 8684171 = 8684178
31 + 8684147 = 8684178
47 + 8684131 = 8684178
67 + 8684111 = 8684178
71 + 8684107 = 8684178
79 + 8684099 = 8684178
89 + 8684089 = 8684178

Showing the first eight; more decompositions exist.
