Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729882, here are decompositions:

13 + 8729869 = 8729882
43 + 8729839 = 8729882
61 + 8729821 = 8729882
193 + 8729689 = 8729882
223 + 8729659 = 8729882
241 + 8729641 = 8729882
643 + 8729239 = 8729882
661 + 8729221 = 8729882

Showing the first eight; more decompositions exist.
