Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637882, here are decompositions:

13 + 8637869 = 8637882
53 + 8637829 = 8637882
61 + 8637821 = 8637882
103 + 8637779 = 8637882
181 + 8637701 = 8637882
241 + 8637641 = 8637882
263 + 8637619 = 8637882
271 + 8637611 = 8637882

Showing the first eight; more decompositions exist.
