Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699640, here are decompositions:

7 + 8699633 = 8699640
29 + 8699611 = 8699640
67 + 8699573 = 8699640
73 + 8699567 = 8699640
83 + 8699557 = 8699640
101 + 8699539 = 8699640
107 + 8699533 = 8699640
127 + 8699513 = 8699640

Showing the first eight; more decompositions exist.
