Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697816, here are decompositions:

5 + 8697811 = 8697816
7 + 8697809 = 8697816
13 + 8697803 = 8697816
19 + 8697797 = 8697816
37 + 8697779 = 8697816
47 + 8697769 = 8697816
109 + 8697707 = 8697816
139 + 8697677 = 8697816

Showing the first eight; more decompositions exist.
