Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644884, here are decompositions:

11 + 8644873 = 8644884
23 + 8644861 = 8644884
41 + 8644843 = 8644884
103 + 8644781 = 8644884
113 + 8644771 = 8644884
181 + 8644703 = 8644884
223 + 8644661 = 8644884
233 + 8644651 = 8644884

Showing the first eight; more decompositions exist.
