Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643960, here are decompositions:

7 + 8643953 = 8643960
19 + 8643941 = 8643960
37 + 8643923 = 8643960
41 + 8643919 = 8643960
67 + 8643893 = 8643960
71 + 8643889 = 8643960
109 + 8643851 = 8643960
139 + 8643821 = 8643960

Showing the first eight; more decompositions exist.
