Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027210, here are decompositions:

3 + 1027207 = 1027210
11 + 1027199 = 1027210
29 + 1027181 = 1027210
47 + 1027163 = 1027210
71 + 1027139 = 1027210
83 + 1027127 = 1027210
113 + 1027097 = 1027210
179 + 1027031 = 1027210

Showing the first eight; more decompositions exist.
