Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697888, here are decompositions:

19 + 8697869 = 8697888
29 + 8697859 = 8697888
37 + 8697851 = 8697888
79 + 8697809 = 8697888
97 + 8697791 = 8697888
109 + 8697779 = 8697888
181 + 8697707 = 8697888
191 + 8697697 = 8697888

Showing the first eight; more decompositions exist.
