Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697984, here are decompositions:

7 + 8697977 = 8697984
11 + 8697973 = 8697984
13 + 8697971 = 8697984
17 + 8697967 = 8697984
37 + 8697947 = 8697984
41 + 8697943 = 8697984
47 + 8697937 = 8697984
83 + 8697901 = 8697984

Showing the first eight; more decompositions exist.
