Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669006, here are decompositions:

13 + 8668993 = 8669006
109 + 8668897 = 8669006
193 + 8668813 = 8669006
223 + 8668783 = 8669006
397 + 8668609 = 8669006
457 + 8668549 = 8669006
487 + 8668519 = 8669006
523 + 8668483 = 8669006

Showing the first eight; more decompositions exist.
