Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645716, here are decompositions:

29 + 8645687 = 8645716
47 + 8645669 = 8645716
59 + 8645657 = 8645716
83 + 8645633 = 8645716
137 + 8645579 = 8645716
173 + 8645543 = 8645716
239 + 8645477 = 8645716
389 + 8645327 = 8645716

Showing the first eight; more decompositions exist.
