Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697856, here are decompositions:

5 + 8697851 = 8697856
23 + 8697833 = 8697856
47 + 8697809 = 8697856
53 + 8697803 = 8697856
59 + 8697797 = 8697856
149 + 8697707 = 8697856
173 + 8697683 = 8697856
179 + 8697677 = 8697856

Showing the first eight; more decompositions exist.
