Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624140, here are decompositions:

3 + 8624137 = 8624140
11 + 8624129 = 8624140
29 + 8624111 = 8624140
89 + 8624051 = 8624140
113 + 8624027 = 8624140
131 + 8624009 = 8624140
137 + 8624003 = 8624140
179 + 8623961 = 8624140

Showing the first eight; more decompositions exist.
