Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658266, here are decompositions:

73 + 8658193 = 8658266
157 + 8658109 = 8658266
163 + 8658103 = 8658266
223 + 8658043 = 8658266
283 + 8657983 = 8658266
433 + 8657833 = 8658266
439 + 8657827 = 8658266
499 + 8657767 = 8658266

Showing the first eight; more decompositions exist.
