Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643256, here are decompositions:

47 + 8643209 = 8643256
59 + 8643197 = 8643256
107 + 8643149 = 8643256
113 + 8643143 = 8643256
173 + 8643083 = 8643256
179 + 8643077 = 8643256
197 + 8643059 = 8643256
233 + 8643023 = 8643256

Showing the first eight; more decompositions exist.
