Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643958, here are decompositions:

5 + 8643953 = 8643958
17 + 8643941 = 8643958
107 + 8643851 = 8643958
137 + 8643821 = 8643958
179 + 8643779 = 8643958
251 + 8643707 = 8643958
311 + 8643647 = 8643958
419 + 8643539 = 8643958

Showing the first eight; more decompositions exist.
