Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617818, here are decompositions:

19 + 8617799 = 8617818
31 + 8617787 = 8617818
137 + 8617681 = 8617818
191 + 8617627 = 8617818
257 + 8617561 = 8617818
269 + 8617549 = 8617818
271 + 8617547 = 8617818
379 + 8617439 = 8617818

Showing the first eight; more decompositions exist.
