Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665884, here are decompositions:

11 + 8665873 = 8665884
67 + 8665817 = 8665884
107 + 8665777 = 8665884
167 + 8665717 = 8665884
181 + 8665703 = 8665884
233 + 8665651 = 8665884
251 + 8665633 = 8665884
281 + 8665603 = 8665884

Showing the first eight; more decompositions exist.
