Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661896, here are decompositions:

7 + 8661889 = 8661896
13 + 8661883 = 8661896
97 + 8661799 = 8661896
127 + 8661769 = 8661896
163 + 8661733 = 8661896
193 + 8661703 = 8661896
223 + 8661673 = 8661896
367 + 8661529 = 8661896

Showing the first eight; more decompositions exist.
