Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665904, here are decompositions:

7 + 8665897 = 8665904
31 + 8665873 = 8665904
127 + 8665777 = 8665904
271 + 8665633 = 8665904
337 + 8665567 = 8665904
433 + 8665471 = 8665904
463 + 8665441 = 8665904
547 + 8665357 = 8665904

Showing the first eight; more decompositions exist.
