Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665518, here are decompositions:

19 + 8665499 = 8665518
47 + 8665471 = 8665518
67 + 8665451 = 8665518
89 + 8665429 = 8665518
109 + 8665409 = 8665518
149 + 8665369 = 8665518
157 + 8665361 = 8665518
241 + 8665277 = 8665518

Showing the first eight; more decompositions exist.
