Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658212, here are decompositions:

19 + 8658193 = 8658212
103 + 8658109 = 8658212
109 + 8658103 = 8658212
229 + 8657983 = 8658212
331 + 8657881 = 8658212
379 + 8657833 = 8658212
601 + 8657611 = 8658212
643 + 8657569 = 8658212

Showing the first eight; more decompositions exist.
