Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006988, here are decompositions:

19 + 1006969 = 1006988
97 + 1006891 = 1006988
109 + 1006879 = 1006988
127 + 1006861 = 1006988
277 + 1006711 = 1006988
337 + 1006651 = 1006988
379 + 1006609 = 1006988
457 + 1006531 = 1006988

Showing the first eight; more decompositions exist.
