Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685228, here are decompositions:

17 + 8685211 = 8685228
29 + 8685199 = 8685228
31 + 8685197 = 8685228
61 + 8685167 = 8685228
67 + 8685161 = 8685228
151 + 8685077 = 8685228
197 + 8685031 = 8685228
269 + 8684959 = 8685228

Showing the first eight; more decompositions exist.
