Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643964, here are decompositions:

5 + 8643959 = 8643964
11 + 8643953 = 8643964
23 + 8643941 = 8643964
41 + 8643923 = 8643964
71 + 8643893 = 8643964
113 + 8643851 = 8643964
167 + 8643797 = 8643964
257 + 8643707 = 8643964

Showing the first eight; more decompositions exist.
