Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697808, here are decompositions:

5 + 8697803 = 8697808
11 + 8697797 = 8697808
17 + 8697791 = 8697808
29 + 8697779 = 8697808
101 + 8697707 = 8697808
131 + 8697677 = 8697808
167 + 8697641 = 8697808
227 + 8697581 = 8697808

Showing the first eight; more decompositions exist.
