Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667882, here are decompositions:

11 + 8667871 = 8667882
19 + 8667863 = 8667882
53 + 8667829 = 8667882
61 + 8667821 = 8667882
73 + 8667809 = 8667882
89 + 8667793 = 8667882
149 + 8667733 = 8667882
193 + 8667689 = 8667882

Showing the first eight; more decompositions exist.
