Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634040, here are decompositions:

59 + 8633981 = 8634040
83 + 8633957 = 8634040
89 + 8633951 = 8634040
101 + 8633939 = 8634040
179 + 8633861 = 8634040
197 + 8633843 = 8634040
263 + 8633777 = 8634040
293 + 8633747 = 8634040

Showing the first eight; more decompositions exist.
