Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636928, here are decompositions:

5 + 8636923 = 8636928
7 + 8636921 = 8636928
11 + 8636917 = 8636928
17 + 8636911 = 8636928
19 + 8636909 = 8636928
29 + 8636899 = 8636928
59 + 8636869 = 8636928
71 + 8636857 = 8636928

Showing the first eight; more decompositions exist.
