Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640950, here are decompositions:

61 + 8640889 = 8640950
67 + 8640883 = 8640950
79 + 8640871 = 8640950
127 + 8640823 = 8640950
151 + 8640799 = 8640950
163 + 8640787 = 8640950
211 + 8640739 = 8640950
271 + 8640679 = 8640950

Showing the first eight; more decompositions exist.
