Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665966, here are decompositions:

17 + 8665949 = 8665966
53 + 8665913 = 8665966
149 + 8665817 = 8665966
167 + 8665799 = 8665966
263 + 8665703 = 8665966
317 + 8665649 = 8665966
347 + 8665619 = 8665966
383 + 8665583 = 8665966

Showing the first eight; more decompositions exist.
