Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756040, here are decompositions:

19 + 8756021 = 8756040
31 + 8756009 = 8756040
43 + 8755997 = 8756040
67 + 8755973 = 8756040
89 + 8755951 = 8756040
103 + 8755937 = 8756040
127 + 8755913 = 8756040
149 + 8755891 = 8756040

Showing the first eight; more decompositions exist.
