Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640948, here are decompositions:

37 + 8640911 = 8640948
59 + 8640889 = 8640948
61 + 8640887 = 8640948
89 + 8640859 = 8640948
131 + 8640817 = 8640948
149 + 8640799 = 8640948
167 + 8640781 = 8640948
181 + 8640767 = 8640948

Showing the first eight; more decompositions exist.
