Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640962, here are decompositions:

13 + 8640949 = 8640962
73 + 8640889 = 8640962
79 + 8640883 = 8640962
103 + 8640859 = 8640962
139 + 8640823 = 8640962
163 + 8640799 = 8640962
181 + 8640781 = 8640962
223 + 8640739 = 8640962

Showing the first eight; more decompositions exist.
