Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660886, here are decompositions:

23 + 8660863 = 8660886
67 + 8660819 = 8660886
89 + 8660797 = 8660886
139 + 8660747 = 8660886
163 + 8660723 = 8660886
193 + 8660693 = 8660886
197 + 8660689 = 8660886
229 + 8660657 = 8660886

Showing the first eight; more decompositions exist.
