Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661016, here are decompositions:

29 + 8660987 = 8661016
47 + 8660969 = 8661016
83 + 8660933 = 8661016
107 + 8660909 = 8661016
197 + 8660819 = 8661016
263 + 8660753 = 8661016
269 + 8660747 = 8661016
293 + 8660723 = 8661016

Showing the first eight; more decompositions exist.
