Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624040, here are decompositions:

13 + 8624027 = 8624040
17 + 8624023 = 8624040
23 + 8624017 = 8624040
31 + 8624009 = 8624040
37 + 8624003 = 8624040
71 + 8623969 = 8624040
79 + 8623961 = 8624040
101 + 8623939 = 8624040

Showing the first eight; more decompositions exist.
