Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697724, here are decompositions:

17 + 8697707 = 8697724
41 + 8697683 = 8697724
47 + 8697677 = 8697724
83 + 8697641 = 8697724
137 + 8697587 = 8697724
173 + 8697551 = 8697724
317 + 8697407 = 8697724
461 + 8697263 = 8697724

Showing the first eight; more decompositions exist.
