Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645706, here are decompositions:

19 + 8645687 = 8645706
37 + 8645669 = 8645706
53 + 8645653 = 8645706
59 + 8645647 = 8645706
73 + 8645633 = 8645706
89 + 8645617 = 8645706
109 + 8645597 = 8645706
127 + 8645579 = 8645706

Showing the first eight; more decompositions exist.
