Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630040, here are decompositions:

11 + 8630029 = 8630040
37 + 8630003 = 8630040
59 + 8629981 = 8630040
79 + 8629961 = 8630040
113 + 8629927 = 8630040
131 + 8629909 = 8630040
149 + 8629891 = 8630040
151 + 8629889 = 8630040

Showing the first eight; more decompositions exist.
