Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647944, here are decompositions:

7 + 8647937 = 8647944
17 + 8647927 = 8647944
31 + 8647913 = 8647944
47 + 8647897 = 8647944
127 + 8647817 = 8647944
191 + 8647753 = 8647944
233 + 8647711 = 8647944
433 + 8647511 = 8647944

Showing the first eight; more decompositions exist.
