Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670210, here are decompositions:

13 + 8670197 = 8670210
19 + 8670191 = 8670210
53 + 8670157 = 8670210
83 + 8670127 = 8670210
103 + 8670107 = 8670210
139 + 8670071 = 8670210
173 + 8670037 = 8670210
179 + 8670031 = 8670210

Showing the first eight; more decompositions exist.
