Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697918, here are decompositions:

17 + 8697901 = 8697918
29 + 8697889 = 8697918
59 + 8697859 = 8697918
67 + 8697851 = 8697918
107 + 8697811 = 8697918
109 + 8697809 = 8697918
127 + 8697791 = 8697918
139 + 8697779 = 8697918

Showing the first eight; more decompositions exist.
