Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624158, here are decompositions:

5 + 8624153 = 8624158
17 + 8624141 = 8624158
29 + 8624129 = 8624158
47 + 8624111 = 8624158
107 + 8624051 = 8624158
131 + 8624027 = 8624158
149 + 8624009 = 8624158
197 + 8623961 = 8624158

Showing the first eight; more decompositions exist.
