Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661026, here are decompositions:

43 + 8660983 = 8661026
79 + 8660947 = 8661026
97 + 8660929 = 8661026
139 + 8660887 = 8661026
163 + 8660863 = 8661026
229 + 8660797 = 8661026
337 + 8660689 = 8661026
373 + 8660653 = 8661026

Showing the first eight; more decompositions exist.
