Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665540, here are decompositions:

41 + 8665499 = 8665540
71 + 8665469 = 8665540
89 + 8665451 = 8665540
131 + 8665409 = 8665540
167 + 8665373 = 8665540
179 + 8665361 = 8665540
227 + 8665313 = 8665540
263 + 8665277 = 8665540

Showing the first eight; more decompositions exist.
