Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658206, here are decompositions:

3 + 8658203 = 8658206
13 + 8658193 = 8658206
97 + 8658109 = 8658206
103 + 8658103 = 8658206
163 + 8658043 = 8658206
223 + 8657983 = 8658206
283 + 8657923 = 8658206
373 + 8657833 = 8658206

Showing the first eight; more decompositions exist.
