Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665944, here are decompositions:

5 + 8665939 = 8665944
11 + 8665933 = 8665944
13 + 8665931 = 8665944
31 + 8665913 = 8665944
47 + 8665897 = 8665944
71 + 8665873 = 8665944
127 + 8665817 = 8665944
167 + 8665777 = 8665944

Showing the first eight; more decompositions exist.
