Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661852, here are decompositions:

11 + 8661841 = 8661852
13 + 8661839 = 8661852
53 + 8661799 = 8661852
83 + 8661769 = 8661852
109 + 8661743 = 8661852
149 + 8661703 = 8661852
163 + 8661689 = 8661852
179 + 8661673 = 8661852

Showing the first eight; more decompositions exist.
