Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618000, here are decompositions:

7 + 8617993 = 8618000
67 + 8617933 = 8618000
73 + 8617927 = 8618000
163 + 8617837 = 8618000
373 + 8617627 = 8618000
439 + 8617561 = 8618000
487 + 8617513 = 8618000
619 + 8617381 = 8618000

Showing the first eight; more decompositions exist.
