Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624178, here are decompositions:

19 + 8624159 = 8624178
37 + 8624141 = 8624178
41 + 8624137 = 8624178
47 + 8624131 = 8624178
67 + 8624111 = 8624178
127 + 8624051 = 8624178
151 + 8624027 = 8624178
239 + 8623939 = 8624178

Showing the first eight; more decompositions exist.
