Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665988, here are decompositions:

139 + 8665849 = 8665988
211 + 8665777 = 8665988
271 + 8665717 = 8665988
337 + 8665651 = 8665988
421 + 8665567 = 8665988
547 + 8665441 = 8665988
619 + 8665369 = 8665988
631 + 8665357 = 8665988

Showing the first eight; more decompositions exist.
