Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661210, here are decompositions:

7 + 8661203 = 8661210
13 + 8661197 = 8661210
17 + 8661193 = 8661210
29 + 8661181 = 8661210
37 + 8661173 = 8661210
73 + 8661137 = 8661210
149 + 8661061 = 8661210
163 + 8661047 = 8661210

Showing the first eight; more decompositions exist.
