Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605986, here are decompositions:

23 + 8605963 = 8605986
47 + 8605939 = 8605986
73 + 8605913 = 8605986
113 + 8605873 = 8605986
157 + 8605829 = 8605986
163 + 8605823 = 8605986
173 + 8605813 = 8605986
197 + 8605789 = 8605986

Showing the first eight; more decompositions exist.
