Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597666, here are decompositions:

19 + 8597647 = 8597666
37 + 8597629 = 8597666
43 + 8597623 = 8597666
67 + 8597599 = 8597666
79 + 8597587 = 8597666
139 + 8597527 = 8597666
193 + 8597473 = 8597666
313 + 8597353 = 8597666

Showing the first eight; more decompositions exist.
