Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665128, here are decompositions:

5 + 8665123 = 8665128
19 + 8665109 = 8665128
29 + 8665099 = 8665128
89 + 8665039 = 8665128
97 + 8665031 = 8665128
107 + 8665021 = 8665128
137 + 8664991 = 8665128
149 + 8664979 = 8665128

Showing the first eight; more decompositions exist.
