Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697886, here are decompositions:

17 + 8697869 = 8697886
53 + 8697833 = 8697886
83 + 8697803 = 8697886
89 + 8697797 = 8697886
107 + 8697779 = 8697886
179 + 8697707 = 8697886
347 + 8697539 = 8697886
383 + 8697503 = 8697886

Showing the first eight; more decompositions exist.
