Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697840, here are decompositions:

7 + 8697833 = 8697840
17 + 8697823 = 8697840
29 + 8697811 = 8697840
31 + 8697809 = 8697840
37 + 8697803 = 8697840
43 + 8697797 = 8697840
61 + 8697779 = 8697840
71 + 8697769 = 8697840

Showing the first eight; more decompositions exist.
