Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655882, here are decompositions:

5 + 8655877 = 8655882
13 + 8655869 = 8655882
23 + 8655859 = 8655882
41 + 8655841 = 8655882
73 + 8655809 = 8655882
113 + 8655769 = 8655882
149 + 8655733 = 8655882
163 + 8655719 = 8655882

Showing the first eight; more decompositions exist.
