Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697660, here are decompositions:

19 + 8697641 = 8697660
47 + 8697613 = 8697660
53 + 8697607 = 8697660
61 + 8697599 = 8697660
73 + 8697587 = 8697660
79 + 8697581 = 8697660
109 + 8697551 = 8697660
149 + 8697511 = 8697660

Showing the first eight; more decompositions exist.
