Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640954, here are decompositions:

5 + 8640949 = 8640954
43 + 8640911 = 8640954
67 + 8640887 = 8640954
71 + 8640883 = 8640954
83 + 8640871 = 8640954
131 + 8640823 = 8640954
137 + 8640817 = 8640954
167 + 8640787 = 8640954

Showing the first eight; more decompositions exist.
