Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009986, here are decompositions:

23 + 1009963 = 1009986
59 + 1009927 = 1009986
113 + 1009873 = 1009986
127 + 1009859 = 1009986
149 + 1009837 = 1009986
167 + 1009819 = 1009986
179 + 1009807 = 1009986
199 + 1009787 = 1009986

Showing the first eight; more decompositions exist.
