Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636946, here are decompositions:

23 + 8636923 = 8636946
29 + 8636917 = 8636946
37 + 8636909 = 8636946
47 + 8636899 = 8636946
53 + 8636893 = 8636946
89 + 8636857 = 8636946
107 + 8636839 = 8636946
127 + 8636819 = 8636946

Showing the first eight; more decompositions exist.
