Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661882, here are decompositions:

11 + 8661871 = 8661882
41 + 8661841 = 8661882
43 + 8661839 = 8661882
83 + 8661799 = 8661882
113 + 8661769 = 8661882
139 + 8661743 = 8661882
149 + 8661733 = 8661882
179 + 8661703 = 8661882

Showing the first eight; more decompositions exist.
