Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697646, here are decompositions:

5 + 8697641 = 8697646
47 + 8697599 = 8697646
59 + 8697587 = 8697646
107 + 8697539 = 8697646
137 + 8697509 = 8697646
239 + 8697407 = 8697646
257 + 8697389 = 8697646
383 + 8697263 = 8697646

Showing the first eight; more decompositions exist.
