Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609998, here are decompositions:

11 + 8609987 = 8609998
71 + 8609927 = 8609998
107 + 8609891 = 8609998
149 + 8609849 = 8609998
179 + 8609819 = 8609998
269 + 8609729 = 8609998
311 + 8609687 = 8609998
347 + 8609651 = 8609998

Showing the first eight; more decompositions exist.
